Double Debited & not refunded

H&M Pavillion Mall- Their staff are not trained well and it causes inconveniences for the clients. On 13 May I was double debited because the teller did not know how to effectively change paper and assumed it was broken- she did not effectively cancel the payment and therefore I had to pay again thinking she already cancelled my payment. Upon returning to the store after noticing the double debit I was made to feel like a ******** by the manager who did not even enquire with the lady who helped me if she did reverse payment which she didn’t know how to do in the first place. overall it completely ruined my entire Mother’s Day budget and I am still waiting for my money to be reimbursed and for the manager to follow up with a conclusion. At the end of the day brand loyalty can be dissolved just by one experience that can leave a bad taste in your mouth.
