Signal now 90% of the time on EDGE

The signal on Vodacom's network used to be LTE in the area where I live. Now it runs on EDGE roughly 90% of the time. I used to be able to perform most of my work from home, but since the signal decreased to EDGE, this is now nearly impossible. <br> <br> If it were peak holiday season, this could have easily been explained by cell shrinkage, but as it is now quite out of season, with very few holidaymakers here, the poor signal is NOT attributable to just too many people on the network. <br> <br> I reported the problem to Vodacom's call centre on or around the 29th of May, and was informed that Vodacom has a problem in KZN, and it would soon be resolved. How much longer will it take before I can have at least 3G or HSDPA here again most of the time???
