Mindinsole Swell EComm Entetprises Charged card twice for 1 order and will not refund the 2nd charge London England

Ordered insoles total 79.19 and was charged twice for 1 order. Upon calling and emailing proof they charged card twice they still have not refunded card. That’s been 5 days of holding for hours at a time plus multiple emails with no reply. They finally had cs agent LeeAnn tell me she would have card credited on that specific day. Guess what no refund. Again I’m sitting in the phone waiting for a customer service agent. I should have read the enormous bad reviews about this company that states they are in USA and are actually out of the UK. 83.00 thrown out the window. I’m on a fixed income and can not afford that kind of loss.
