An email was sent on the 14th December, complaining about the bad signal we are experiencing at our home.<br> To date, no response!<br> <br> Good day<br> <br> We have recently moved to Johannesburg - Florida Glen and we are struggling very much with poor or no service at our home. My wife is working from home and her phone bill has increased due to the fact that she is experiencing many dropped calls due to bad service. She is also using mobile data and her production time has slowed down tremendously due to bad signal or no service at all. We have been clients with Vodacom since 2001 and would like to know if there are anything you can do to assist us in this regard<br>
