Cancellation against my will and have to pay the bill

I have two contracts with Vodacom, one is for my mobile phone and the other for Wifi. Everything had been goung smooth until i started experience slow to none existing wii access. i called vodacom on several occassions to alert them of such. I would be given a ticket everytime, before the issue was resolved the ticket will closed, with the status RESOLVED. Which was not the case. A manager called me to find out if the problem had been solved, which wasn't solved. on the phone she mentioned that the problem was the router, i asked why were faulty routers sent tocustomers? there was no answer there. iI told her i chose Vodacom for a service not to be told excuses and expect them to deliver that service to me as i was paying for a service. She told me a technician will be sent over to my residence to investigate the issue. That took ages to happen until rang again, of which one of the agents told me that the tower near me needed upgrading and the Vodacom was waiting for the Municipality to approve their plan to take place, in the meantime i was paying them full price.

The technician did finally made his way to my residence(Mokoena) he confirmed that our speed was indeed to low and the internet was slow. No feed back from vodacom until i got an email telling me that my Wifi had been downgraded to prepaid and there was a bill of R3800 that i needed to pay. when and how when i've been patient with Vodacom. I feel ****** and cheated by vodacom. They have now disconnected my mobile phone contract which has nothing to with the Wifi. I asked them to send me call recordings of me asking for a cancellation and i'm still waiting.

I am seeking legal representation in order to sort this mess.
