I am quite disappointed, take an issue with the way costco store supervisor Riya behaved when we raised the issue of double charged transaction with her on 14/10/2022 at the Western International Park, Hayes Road Hayes London She was Rude and patronising and tried to teach us how banking works in our own bank account when we showed her our online bank account and double charged transactions. Her misrepresentation that the money will not be debited from pending has caused us financial loss and I suspect Fraud by misrepresentation committed by Costco via their supervisor Riya. On 17/10/2022, after 3 days, as the money was not returned, I had to go back to Costco store but there the Store Manager was even more condescending and sarcastic . This is clear indication that they do not intend to refund my money and is proof of purposeful fraud committed by CostCo and its staff. I have called many times and visited multiple times to no vail. Your failure to act promptly to refund the money you took fraudulently from us further confirms our suspicions of Fraud and means that we have no other option but to resort to other means. Therefore, we are now seeking our money back plus compensation for the overdraft charges and interest through legal means under Consumer Rights Act that includes but not limited to small claims court claim without Prejudice. I shall also report Costco to Police for Fraud through their supervisor and also report to Trading Standards of UK. I am absolutely appalled by costco's refusal or lack of action to refund our money and their supervisor Riya, who was more occupied with telling my husband “Don’t Shout” when he was not shouting than concentrate on the issue. He was just explaining the situation. This was clearly to hide the fraud she was committing in collaboration with Costco.
