ZERO RESPONCE on moneys taken wrongly

A debit was made on my account, for an old fuel card, that was paid up in 2007/8, and for a filling station area I have never been to. Many promises from their complaints division, and ZERO help from their call centre. The wording states, we can see the money should not have been taken, BUT NO ONE can sort it out. Should we sound like the EFF, pay back the money?
