terrible service again from mweb

Terrible service experience, I initially had a 40gig line with vuma tel @R529 P/M, an agent advised that I can change contract to an open serve line for R329 P/M, I was excited on the offer as he advised that everything will be the same in terms of my requirements therefore I proceeded with the new contract, only to realize upon installation that the open serve router is programmed to accept one Lan cable which I was not informed on the call. My current set up had two lan cables one for my extended router and the other for my security cameras. The product was mis sold to me , I was inconvenienced with regards to poor connectivity as i could not use my extended router due to some places in my property not picking up connectivity. Furthermore , the installation was very untidy. Another agent did contact me a few days after installation from the onboarding team , I expressed my dissatisfaction and she advised that she will get the sales consultant to contact me , to date no call recieved , I had to call myself and in the last three weeks i called about five times , eventually one agent assisted with reconnecting the initial contract with Vuma and another agent from cancellations advsied that an immediate cancellation can be done on the open serve contact as std terms is 30day notice but due to incorrect advice I was not prepared to pay for another 30days as I will paying for the Vuma line, i called again requesting feedback and another agent the open serve line is still active, the agent that did connect Vuma advised she will send me an email whcih I have not recived yet , and the most frustrating part is that every time I call I hold for minimum 20 min and then I speak to an agent and they transfer to you to the cancellation team which you hold for another 15 min , I easily spent about R100 worth of airtime trying to call for feedback but didnt even get through to someone, its actually apalling to experience service of this note constantly, to other consumers , please make sure before signing up that the routers meet your requirements as you can get easily mis informed which causes much inconvenience considering the after sales support is so inefficient. If mweb does read this review, please can a manager contact me urgently as I need the open serve line to be cancelled immediatley,
