Poor signal

Since 2013 I have been reporting poor or no signal coverage in Riversdale, Meyerton, there was promised that it would be sorted out. Until today I cannot use internet or a call without it been dropped, I have been promised that either a new tower would be put up or adjustments made. Not a single technician has come out in 2 years to come and access on site. Extremely poor service from Vodacom. I have been with Vodacom for more than 16 years and it may be time to change service provider.
