Done with MWEB ****py service

I have been trying ti get assistance from MWEB for the past three months and rather I have dealt with people who seemed clueless with what they are doing and another one who **** by saying that they will call me before 17:00 and they never did a woman called Brenda and Tian from the technical team department. I took the contract because I am studying and needed internet access without having to hotspot.

I am highly disappointed with the service, I was given a replacement Sim/ Sim swap and this hasn't worked since the 31st of January that it was delivered, I have made numerous calls to MWEB everyday either to no avail or never getting the answers that I need and getting promises which are never kept. I have expressed my desire to cancel the contract and instead of getting someone who was willing to assist Brenda posed as that person promising to call me on January 8, 2019 before 17:00 she never did and at this time I am tired of trying and begging for the service that I have been paying for and not getting anything from. Today I have called about 5 times and stayed on the line and getting someone transfer me only to have my call go unanswered. I don't need anything from them but to terminate this contract, return their router and find another service provider.
