Refusal

I am writing regarding a booking I made and paid for via FlexClub. Upon arrival at the Avis branch, I was unfortunately not able to be assisted due to my credit profile, which I understand. All this could have been mentioned before I actually paid

I was informed that the refund would be processed within 15 days. Unfortunately, I am not in a position to wait that long. My work requires extensive travel, and without a vehicle at my disposal, I am currently unable to work. Customer care is non existent even after I have sent several emails. I need my money back so I can make alternative arrangements
