Worst network in SA MTN

Been trying to cancel a contract which was up due for upgrade, because I haven't used it in months. Been trying for over a week to cancel it, but just get sent from one person to next and they ask the same question and then you get another email. All the mean while i get billed for it, they are a **** and I am going to cancel all my contracts with them. Service is terrible and network coverage is even worse. Do not use them for any reason, telkom and vodacom are much better. Sent email to all the departments but just get - • ID Number • Postal / Residential Address • Work Telephone Number / Email address • Bank Name / Type of account Then nothing happens after that. PS you can block their debit order on your bank, don't pay for a service you do not want or need too.
