Unsatisfactory Service

I had basically my whole contract period issues with MTN not deducting my monthly premiums on the correct date, or not informing me that a debit order did not go through. I made a payment of R910.00 which settled my account up to date, after which no debit orders was deducted and once again I was not informed. Only when I went to the Knysna MTN branch did they inform me that I am behind an amount of R650.00 , which I then (11/04/2018) paid once again in full, settling my account. My account was never after that activated again even though I contacted MTN custormer care. For the month of May 2018 I once again picked up that no debit order went off. I went again to the Knysna MTN branch settling again my account with R270.00 (02/05/2018) When I asked the assistant why this debit order did not go off he stated that a debit order was requested but due to insufficient funds did not go off, which is a blatant lie as I had more than sufficient funds in my bank account as from 24/04/2018, unless due to MTN's total incompetence, making this request from a wrong bank account!!!!! I am really disappointed in MTN's service and will be closing my account once my contract period expires and will definitely make sure that none of my friends or family consider this service provider as a future contract option. PLEASE NOTE THAT MY ACCOUNT IS STILL NOT ACTIVATED - CAN THIS BE DONE!!!!
