Billing: Is there no credit for the fees I have already paid?

I just upgraded my account from bronze to silver. I did not see a credit for my previous payment. I paid $114 on 12/5/2020 and upgraded to silver today for $234. Don't I get a credit for the fees I have already paid?

Hi rmhall, thank you for reaching us.

Please kindly allow me some time to get in touch with our billing team. We will notify you through this ticket soon.

We have sent a refund request for the Bronze subscription payment. Please expect the refund in 5 to 7 business days.

Thanks!
