In answer to the original question I would go down small claims court route
I had to do this when we were ripped off before our wedding. Mrs Sinatra purchased some bits for her wedding outfit (mail order) and we mistakenly paid by debit card. Cost was £250. Goods turned up, then a second payment was taken. Company went underground, couldn’t contact them and before we could sort things with the bank, a third payment was taken.
Eventually went down small claims route. Filled in the forms, cycled down to Sheriff Court o and arrived in the right office slightly sweaty from the ride. The Clerk offered to check the forms for me. He skimmed through them then, in a room full of solicitors, staff and other members of the public said, in a very loud voice, ‘So, your claim relates to your purchase of a ladies corset, in baby pink? I wouldn’t have thought that was your best colour Sir…’
Anyway, the claim was settled very quickly without going to court
