Mtn pavilion

I opened a wifi bundle contract with mtn pavilion on the 11th of March and it has not been working. The wifi connects but says "no internet access". I tried calling mtn pavilion at first but they never answer no matter how many times you call. On the 17th of March I went they and they told me that the sim card had not been registered with Rica and said they have logged a call and it should be fixed by Monday(19 March). But a friend of mine who has the same mtn bundle which had the same problem as mine went to mtn Musgrave and the Rica problem was fixed in a matter of minutes. I went back to mtn pavilion on the 18th of March and the manager, and two employees could not explain to me why mtn Musgrave can fix a problem in a few minutes and they cannot. The manager tells me it will be fixed on the 19th and the technician tells me "maybe Monday maybe Tuesday". I asked to close the contract altogether as I do not want to be with mtn anymore and they refused. The technician told me they do not do contract cancellations and you have to forcefully keep the 2 year contract even if you don't want it.
