Terrible customer service when calling them regarding an overcharge in store. The first phone call went well and advised that accounts would call within an hour. They did not call. 2nd call the man talked over me much of the time and insisted I send images of the receipt as proof, I find they have a sophisticated IT system with transaction number and other information on receipt that can identify and easily look and confirm that I was charged for 2 identical items instead of 1. For a 5* business this was Asda style service on the phone. Still not resolved, I have spent more time on this than the amount owed justifies. My tip if buying in store, do not use cash and calculate in advance of the till your approximate spend. They make mistakes, human error and punish the customer if you try and rectify at home.
