Vodacom's answer, to my repeated, ignored requests for assistance, is to cancel my contract!!!

I was told by Vodacom's customer call centre this week that I should cancel my contract seeing that my problem have not been resolved after trying to get Vodacom to address it for four months!!! I was speechless. I have been a Vodacom customer since it first opened its doors. For the past four months I have been reporting a booster and signal problem to no avail. I would get messages stating that "the problem is being addressed", "it has been escalated", "a technician would be in contact", etc. only to receive messages the next day that "the ticket has been closed and the problem has been resolved"! I have lost count of the number of calls. This constant struggle has been exhausting. I left it for about a month and then finally tackled the issue again this week... only top be told the solution is to cancel my contract! I am shocked to say the least. As all Vodacom users know, the service has been ********** the past couple of months and signal problems are reported countrywide. I would like to know if this is now Vodacom's general attitude to loyal customers? And I really expect an answer. It is the least Vodacom can do as I have a contract I have to pay every month without getting the services.
