My Name Is Basel Abbas I am an Avant Card Holder, On the Morning of May 15th, 2019 I went to buy breakfast for my daughters I did not have my wallet on me all what I had in my car is Avant card after checking the credit on my online account via Avant website it stated that I have $19 in credit so I went and bought breakfast for my daughters the bill came to $8 and some change. | The Mcdonald Employee informed me that the card is declined, I ask him to try it again it didn’t go through So I HAD TO TAKE THE FOOD FROM MY DAUGHTERS TABLE BACK !!!! How is it that I can not use the credit when I have it I called customer service The worst customer service on this planet the first time they said that it is the merchant error!! Then they said that I can not use my credit when My payment was due on the 13th even though I scheduled my payment for the 17th. | I asked the customer service lady I should have 10 day grace period they said no so I asked are they going to take my payment from my credit???? they kept me on the phone telling me lies after lies 48 minutes later I talked to Dentanio he identified himself as the ops manager of that place and he kept saying I will send your complaint to the escalation team. This is the worst experience that I’ve ever had in my life since when we can not use the credit that it says it is available ??
