Unable to cancel my contract with them do to poor service

1 - Customer call centre takes 40min to take a call. Extremely long. The operator transferred me and dropped my call, I had to call again and wait another 40 min. 2 - Rates of landline went up drastically without informing their customers. The amount looked suspect, I called the call centre who could not identify what the cost was for. I then stopped the debit order because it looked **********. 3 - After 3 months, I get a notice on my mobile phone that I am handed over to the attorneys for not paying my account. 4 - Went to the store to pay my account and close it. It is not possible to do it at Telkom. I had to go to Woolworths. 5 - I cannot close my account in the store, I had to register online to close my account. 6 - After online registration, I was unable to link the device to my account because they could not identify me as a valid contact for the service on the account. 7 - Unable to close the account, I try to chat with online chat. After failed three attempts to chat with someone, I opted to phone their call centre. 8 - Following the call centre options, as soon as you select cancellation of service. The audio informs you to register online and cancel it their. That was the reason why I phoned in the first place. There is no option to put you through to an agent.
