Mweb bad service

Our wifi has been off for 2 weeks, we called mweb tech support several times and went through more than R500 airtime without any answer, we sent emails and also got not answer, eventually my husband got through and he followed all the steps given by the technician without success, the technician then told my husband he connected us to a different tower and if the wifi still does not work we have to contact mtn ourselves. We pay mweb for wifi not mtn so why do we have to contact mtn?? We pay mweb and they should call mtn and sort this out. Now we want to cancel the wifi but have to pay 1 month notice, so basically we will have to pay for a whole month and have no wifi. Mweb your service is terrible and I will NEVER recommend you to anyone.
