Bad to no service from Vodacom

I have reported bad reception and missed calls in our area for some time now. The first generic answer I got is that they will get back to me within 4-5 days. Not even they are able to get hold of me because of the calls not ringing through. I have requested that they install a signal booster as this is an ongoing problem and people in our area are busy with a petition. We pay subscriptions but don't receive any service. Totally frustrated because everytime you make an enquiry you just get a generic answer that they are still investigating. This problem has been with us for a long time now but got worse as time has gone by. Could we get some useful info regarding the problem and action taken to improve the service.
