Bad Credit

This is the first time I have a contract with MTN. They debit order the wrong amount and my account went into an arrears! The cherry on top is they affected my credit so bad within three months of having this account, I don’t qualify for anything!!! Call the call centre and they said it will take up to 30 days. I regret going into business with them. I’ve never had any of this issues with Telkom and Vodacom
