******* Debit Orders

My contract was due for upgrade. I have had my contracts with MTN for 15 years. I have always paid cash. In May an agent called me to upgrade my contract. I declined after the contract was not suitable. He requested my banking details which I provided however I advised him I pay cash. At the end of May a debit order was requested and declined as I had insufficient funds in that account. I called several times to dispute the debit order to no avail. Today an agent said it may be ***** and that my account is with legal because the debit order was returned. She advised however she can see that my account was paid in cash. She attempted to transfer me to ***** division and the call was dropped. I chose to pay cash as when I commenced with the contract I had double debits being deducted etc.
