Disgusting customer service

Ordered from Milady’s online and had to return to a store for credit as the items did not fit. What a disaster...3 shop assistants could not process the credit back to my credit card! 60 min later left the store with my goods and totally frustrated. Tried to convince them to phone head office to see what they were doing wrong.....no reply? They tried to get me to accept vouchers which I defiantly did not want as I had paid cash. Totally unhelpful and not at all prepared to resolve my issue.sent an email to customer services who don’t even have the decency to respond. Miladys obviously don’t need my business?
