Hi I purchased my Xbox series S on takealot and was eligible for a free 3 month game pass...

Is this the store?
https://www.takealot.com/help-centre

If yes, you can use their support website to reach the seller in case you’re not able to see the option in your order history

Hi how do I contact the store because like I said I purchased it on Takealot

If your console has a digital reward you can claim it in this way:

“Select Settings > Account > Included with this Xbox to see an overview of and redemption status of any Digital Direct offers included with your console.”

If nothing appears you need to reach the store and ask for this 3 month game pass reward

I had just bought the Xbox series s starter bundle but I can’t access my 3 months of Xbox game pass. It’s not anywhere on the Xbox

I searched too and I couldn’t find me 3 months game pass neither

Also it’s not a trial. I bought the Xbox Series S starter bundle with one controller and a 3 month ultimate game pass
