Incredible Bad Service

All outgoing facilities on my cell phone were suspended today due to non payment. I recently switched bank accounts and notified MTN of my new bank and account numbers etc. I knew I had and still have sufficient funds in my account to cover the debit order. When I phoned to ascertain why my service had been suspended I was informed that my bank account was frozen .....Told Jason the phone consultant this was not true as I had used my account this very morning and that there had always been funds in my account.He said I should contact my bank ,which I did and there has always been several thousand in the account. I phoned MTN back and explained situation...sufficient funds etc. Send through a debit order and reconnect my service. Response was go to any MTN branch or ABSA to make payment. Rushed off to the Davenport Square to make payment and was told they do not accept cash...or card....or any payments...I must go to ABSA . ABSOLUTELY disgusted with MTN.....YOU need to catch a huge wake up and point out branches where payments can be made etc....
