Rainbow Shops review: the amount I paid for a dress was not fully credited to my account.

I returned a dress because it was a poor fit on August 11, 2019. I was not credited the full amount of the purchase. Granted it was only $.60 but the reason for not crediting my account was that it was TAX FREE WEEK. I was credited $9.97 but I paid $10.57. I believe I should have been credited what I paid for the dress since it was prior to it being TAX FREE WEEK. I cannot upload the receipts in any other format other than a pdf. The receipt numbers are: (purchase receipt) Store #01139 Term #002 Trans #245162 and (return receipt) Store #01139 Term 002 Trans #24559 of which both has my name and address. I know it is only $.60 but what if it had been more than item and the same thing happened?

Thank you in advance for your consideration.
