Update.
It seems since I wrote this, the situation has turned quite sinister.
I have a sinking feeling my debit card has been cloned, I have since had 2 more transactions taken from my account, plus a deposit of £200. All from pay day loaners.
I've cancelled my debit card due to fraud and had another issued. I've also gotten a refund for the Quickquid transactions. The bank then asked me to contact these other two companies, which I did and they had no record of me. (unsurprisingly) The deposit was from Express Loans (believe it or not) and made after the transactions from My Loans and Loans Express and I have since contacted and paid this money back.
Now anyway, despite my bank refunding the transactions from Quickquid they are refusing the other two on the basis they are loan brokers. I've asked for a chargeback and they refused this, on the same grounds. The seem to think that because I did have a ligitimate loan with Quickquid, I used these brokers and a refusing the chargeback. They then said they cannot perform chargebacks on loan brokers anyway.
Any advice?
