My credit card (with no affiliation to a bank) has been fraudulently used for Microsoft...

I'm surprised that they didn't tell you that reporting the card as lost/stolen or otherwise compromised would stop any additional payments, since it would no longer be possible bill a CC that has been cancelled.

Simply cancelling your current CC (and getting new one issued) should prevent further payments.

I would like to add that these charges are unlikely being made by Microsoft.

Rather someone has probably stolen your credit card information and is using it to buy content fraudulently. If that is the case, only your bank can deal with these transactions.

I never authorised a debit order on my account and i have been overcharged. Please refund the R1503.74 plus R3.00 bank charges

It doesn’t seem that Microsoft is getting involved in this. It might not be a Microsoft transaction at all.

I recommend you get you bank card stopped and report the fraudulent transactions to your bank’s fraud department. If it is through a credit card they should be able to reimburse you.

I also suggest that you find an alternative method of payment for your Microsoft account. My card details have been compromised twice.

if you have a credit or debit card linked to the account, contact your credit card company/bank and cancel the card and make sure there were no fraudulent purchases made by the scammer.
