Discrepancy between Fees, Orders & Payments To Amazon

Amazon took £612.00 from my account on 26/11/21 which i knew they would but it’s not showing on any of their reports as other payments have. I contacted support who could not find the £612.00. but said there were some fees that added roughly to that amount!!!..I then called my bank and sent AMZ the transaction number and then they said please refer to previous answer…apologies it’s not the answer you are looking for…This is nonsense I have done a complete reconcile and the £612.00 is no-where to be seen…what else can i do please?
