No internet access

I went on a bussiness trip to white river and i was unable to get internet signal to operate my laptop. I then went back to nelspruit to try but no internet signal. I was now desperate and phoned Tabo at cresta branch who was busy. Thabo did call me back and said he cant help me and put me through to technical dept. I held on for 47 minutes and no response and my phone cut off as my battery was now flat. This is totally unaceptable to me and i am not receiving the support i should get. On returning to jhb i was able to get the signal again. If this is the case why was i not warned about this problem when i purchased the ****le and i would have gone to another provider where i would not experience this situation. I WONT renew my contract with Mweb when it falls due. I will in the meantime seek legal advice as to what my rights are. SHAME ON YOU MWEB.
