Cell C reception

I have been experiencing bad Cell C reception in Valhalla since November 2015 as communication is interrupted and you cannot hear the person on the other side. I reported the problem to cell C at mall@Reds in November whereby i was informed that hey are currently in process of correcting the signal towers. As from January 2016 my wife that also have a cell c contract started to experience the same reception problems. We have a business to manage and it is becoming difficult to communicate with clients and we have been losing clients due to the communication errors that are occurring. We have since reported the error with the following reference numbers: *** and ***. The query was followed up on 09 February 2016 were the inquiries was still active and not resolved. We then followed-up on the queries again on 13 February 2016 it was still not resolved. We returned to Cell C store at mall@Reds and spoke to the manager at the branch and he did an inquiry himself and the feedback was that they are still in process. We are hereby considering to cancel our contracts and go to a new service provider if we don't get any response from Cell C within 48 hours.
