PHONE KEEPS DROPPING NETWORK

My phone was not connecting to the Cell C network so I called the cell C call center was told that I was on the list to be migrated to the Vodacom network. I was told what do, but for the last 2 weeks I have really been struggling. My phone constantly losses connection, when this happens I can't receive calls, sms's or receive whatsapp messages or surf the net. I have tried to contacted the call center and keep getting cut off. This is the worst network ever. The staff are quick to tell you about their working hours but are not equipped to help with issues. Please tell me if there is a solution to my problem? Am I the only person with this problem.
