Very poor 3G & voice Morningside Jhb

There has been little or no 3G coverage as well as extremely poor voice reception in Morningside Jhb. I have logged 4 calls during the period 12/2/2015 and 19/3/2015. My first 2 calls elicited the response that there didn't appear to be a problem but the matter would be escalated and they would call me within 48hrs - this didn't happen. The 3rd and 4th calls which were 2 weeks apart both advised that there is a problem with the tower feeding Morningside, technicians working on it and should be resolved 2-48hrs. 2 weeks later the problem still exists and of course no feedback from the call centre ***
