Microsoft Canada - Terms of Sale, Pricing. Hidden policy?

Hi - I've been trying, with no success, to have Microsoft Store Canada issue me a credit or refund for a purchase I made, where the identical item was lowered in price within 30 days of my purchase. From Microsoft Store Terms of Sale (I've pasted the whole
pricing section, but highlighted the specific reference):

14. Pricing. If we have a Microsoft Retail Store in your country or region, the prices, product selection and promotions
offered there may be different from those on the online Store. To the extent permitted by applicable law, Microsoft does not guarantee that a price, product or promotion offered online will also be available or honored at a Microsoft Retail Store or vice versa.

The Store does not have a price match guarantee. We will not match the advertised price other retailers offer for the same items. However,
if we lower our price on a device within 30 days of your purchase, we will honor the lower price. If you notice that we have lowered a price on a device you recently purchased, just bring
your original sales receipt back to the place of purchase or contact Sales and Support, as applicable, and we’ll gladly issue a refund or credit for the difference (if you paid with a credit card, you’ll need to use the same card). You must contact Microsoft
within 30 days of the price change to receive the refund or credit. Price reductions/adjustments are not available for clearance items and limited-time price reductions associated with promotions and/or special sale
events including Thanksgiving Day, Black Friday, Cyber Monday or Cyber Week.

We may offer an option to pre-order some products before their availability date. To learn more about our pre-order policies, please see our Pre-Orders page: https://go.microsoft.com/fwlink/p/?linkid=834935&clcid=0x1009.

Unless stated otherwise, prices shown in the Store exclude taxes or charges ("Taxes") that may apply to your purchase. Prices shown in the Store also exclude delivery costs. Taxes and delivery
costs (as applicable) will be added to the amount of your purchase and shown on the check-out page. You are solely responsible for paying such Taxes and costs.

Depending on your location, some transactions might require foreign currency conversion or be processed in another country. Your bank might charge you additional fees for those services when
you use a credit or debit card. Please contact your bank for details.

Here's the situation

1. I purchased an XBOX ONE BUNDLE on March 27. On April 2nd, the same bundle was reduced in price by $100. The identical bundle was available to purchase online. I attempted to call and chat with Microsoft online store several
times since April 2nd to ask for a refund of the difference between my purchase price and the new price. I was unable to reach anyone until Sunday morning, April 5, but still well within the 30 days of the original purchase.

2. The agent informed me that since the bundle I purchased was NO LONGER IN STOCK, they would NOT "gladly issue a refund or credit for the difference",
contradicting their published policy. I did make it clear that I attempted to call/chat several times from when the price dropped and the bundle was still available,
and that they've clearly been busy with the physical stores being closed and that traffic being routed online.

3. The agent agreed that it was reasonable that the bundle I bought could have sold out between when I first attempted to reach out to them for a refund and when I finally reached a person, but insisted they can only issue
the refund or credit for items that are in stock.

4. Since reasonableness and my story was not moving the agent, I simply read the pricing policy, and nowhere does it state the item must be in stock for the refund or credit to be valid. See above. She agreed that requirement
was not stated in the terms of sale, but that, and I quote, "we're Microsoft, we're a big company, we have guidelines that we keep internally, we don't have to share everything with consumers"

5. I asked, how I, as a Microsoft consumer, who made my purchase with them based on publicly published pricing terms, how am I supposed to know about these "hidden" technicalities? She didn't have an answer, simply stating "I've given you the option, and that
option is there is nothing we can do for you".

So I guess my question is - now what? Is there another option within Microsoft to escalate this, or does this do down some consumer affairs rat-hole? I've spent
hours trying to get a simple refund or credit for $100, but this "too bad, our policy says one thing, we can do whatever we want" conclusion is mind-boggling from Microsoft and extremely misleading.

Any help or guidance would be greatly appreciated. (pardon the formatting issues)

Thank you.
