Store Receipt Not Received

I purchased a device from the ATT Wireless store in Stonebriar Mall in Frisco, TX because it was on major sale and I do not live anywhere near the store itself. I need to return it to an ATT store near me; however, they clearly sent the email receipt to the incorrect email address. I was given the option of a paper receipt or an emailed receipt and I opted for the email version because I like to save paper.

I have searched through all of my emails and these happen to be emails that I do not delete but rather save into a receipts folder. I never received the email so I do not have a receipt.

I have the transaction amount and the card number that I used but I desparately need the receipt.

I have called the store for more than 4 hours now and it continues to cycle and indicate the call cannot be completed after cycling through the IVRU prompts indicating that everyone at the store is busy.

Can any employee in this forum assist with this request or at the very least have someone at that store location contact me?
