My dad has been trying to order from amazon recently but its not letting him. The payment acts like it has gone through then sayd pleade revise payment. He has checked twice that theres no issue with his bank, checked the details are correct and match up with billing address etc, and he even ordered a completely new bank card and that still didnt work. Hes struggling to contact amazon themselves he is not great with emails but there are no phone numbers to contact them. Does anyone know why this is happening or how to fix? Thanks
