No Help from Vodacom

I have signal problems in my area. I reported the problem just to find out that there is nothing that can be done and that I as the customer need to buy a booster. So I am in contact with a Vodacom employee to sort this out. It has been 2 week and I have no feedback from Vodacom. I feel like why do I pay for a service that i am not able to use and if trying to cancel a SIM ONLY Contract i need to pay R4000 for nothing. My email to vodacom gets read, but no reply. The employee that is supposed to help me is Tintswalo Ndhlala from the Executive Client Liaison Office.
