Circle K

I purchased a Sip and Save for [protected] phone number from the Circle k, at the 3130 Stockton Hill Kingman Az 86401 store on 1/13/2022. Purchase order number 444060, I have tried to use it on several occasions, but it just keeps asking me to purchase it again. I have tried to contact Circle k through their web site and by phone on several occasions but have gotten no response.
