@op_JOkEr

Did you open a dispute when you tried the code and it didn’t work? You should do that immediately when that happens or the order will eventually finalize.

I have opened one but ive been waiting for almost 2 weeks now for it to be solved its ridicoulous One of the £2 only got refunded today but my £20 is still waiting @op_JOkEr @DunnBiscuit Please solve this for me. I need your help rapid

Hello!

I just checked and answered your tickets.

Thank you.

The 2 $10 need to be checked

Hello!

Both codes are working. So we can’t refund it. As the seller said you will need to contact MS support so they can provide you further help.

If the codes had any issues or were listed wrongly, then i coiuld help. But this isn’t the case.

Thank you.
