Vodacom Bad Service

I have a 36 month LTE contract with Vodacom.

After 10 months the Router (supp**** by Vodacom) started to stop working regularly. I changed the router with an older router that I had and it worked perfectly.

I then took the router to Vodacom. They said they must send it to a repair centre and they will advise when it is ready for collections. After 5 days I received the router and they claimed that there was no fault with the router but they did upgrade it? When I installed it it was worse then before. It now goes off for a few hours at a time

I took it back to the Vodacom store in Greenacres Port Elizabeth where a very unfriendly gentleman advised that they did fix the router and they will not replace it. He then gave me the number of the cancellation department of Vodacom and said that I must call them to cancel the contact. I did not request this,I just needed Vodacom to either repair or replace the modem.

According to articles on Google this specific router does have problems with bad reception. The modem in question is a Huawei router no 4GCPE 3.

I then called the cancelation department of Vodacom only to be told that if I cancel the contract I will have to pay the rental for the months upto36 months. He said that I must take the router back to Vodacom.

So I now need to pay for a service that I cannot use Please assist in resolving this
