Network quality and Strength deterioating

Hi<br> <br> I have been living in my area for about 1 1/2 years. When I moved here I was a loyal customer of MTN, however the signal here was bad, and Vodacom's better. I subsequently ported to Vodacom and the actual network strength increased.<br> <br> My complaint is that in the last 2 months the signal quality has gone to absolute \*******". Most parts of my home I get no service and have to go to specific areas to get 1 bar.<br> <br> I did not move to Vodacom where I was very happy to only be irritated as no-one can get hold of me at my home.<br> <br> Please investigate and rectify ASAP.<br> <br> Disgruntled customer."""
