Unable to allocate my settlement.

My car got ****** on the 19th March. Insurance settled my account on the 26th of March. I phoned the call center sent multiple email to remove and close the account. I have sent the the proof of payment multiple times. Cal center just passes the call from the one *********** agent to the next. on the 1st of April my debit order goes off. Still trying to get the payment allocated and settle the account. Up untill today nothing works, payment made but nothing works, account just keeps on running. I am gatvol for Wesbank and this gives FNB a very poor name working with this useless bank.
