Pathetic service, pathetic consultants

I have opted for vodacom fibre 2 yrs ago and took out lte while waiting 4 activation but then decided to cancel as the service was pathetic. The first incident happend when they cudnt activate the lte because of system issues. I then decided to cancel lte and fibre as i git a better deal elsewhere. The consultant i spoke with confirmed any and all products i had with vodacom was cancelled and i even received a ref no. Only for me to get a statement a year later saying i owe money for lte connection when there was none. I have since spoken to jumerous consultants all saying they cannot find me on the system, and when eventually they do find me, they all confirm that my cancellation was not done and that they will process and yet i am still getting billed, i was even handed over due to this. Evrytime i call i need to explain my situation over n over again getting no results. The calls are obviously recirded so why can they not go to previous calls and here my request and check and see that it was not actioned. I was also advised by a consultant that i cannot just walk into any vidacom shop to have this sorted or cancelled once and for all it has to be done over the ph. I even trued email but no such luck. How long must i wait for this issue to be sorted because i am not paying for a service i did not receive. All hardware is still with me and packaged as the day i received and i am still waiting gor someone from vodacom to collect as i was told they would. So i dont see how this is any longer my problem as i did all i could feom my sude. Vodacom is the worst network i have ever had the misfortune to use. I will gladly take this to court to have it resolved once and for all
