STILL NO FEEDBACK

I registered a complaint about 3-4 weeks ago regarding the bad data coverage we have in our area of residence. The gentleman that called me from Vodacom promised that he would send someone to my residence to check for problems regarding data coverage. I have still not heard anything and the coverage is even worse now. We are lucky to get EDGE !!! We run a business from home and cannot accept this kind of service. Please can someone get back to me urgently regarding this else I must cancel my service and go over to another internet provider.
