Poor service

I have been trying to get vodacom to help us with a signal booster at home for 3 months now. I called numerous times and went into to shop, but seems like no one is willing to help me. I locked a query it took them a month just to tell me my query has been resolved, but they did not do anything. Nobody came to my house to see what kind of booster is required, no phone call, nothing. I then went back to the shop on 3 August and they said they will look into it and I am still waiting for an answer. I still do not have any signal at home. I am so sick of Vodacom's poor service.
