Fuel cards
I held some fuel cards with WEX. They requested £2,000 to be held in their account as cover whilst I built up a credit rating with them. I canceled the account after a month as I found another provider who didn't require a deposit to be held but then WEX didn't want to return the deposit. I was told it would be back with 3 weeks of the closure, I'm currently 5 weeks on and still being told it will be released in 3 weeks time. Joke of a company
