Still ot satisfied with vodacom

Did previously reported to Vodacom and hello Peter the problem in regards to the network signal. Vodacom network engineer did infact call me and promised that they will sent somebody to check out the signal strength not only from where we live, but also the surrounding areas. As to date nobody came back with an reasonable reason for why the signal is week. Also some of our friends staying in Ermelo mphumalanga are struggling with the same problem. Some of our friends has had to change sim cards, yet still having the same issue. This is becoming a serious problem, meaning what if our FAMILY MEMBERS are in trouble, how will they get in touch with emergency personnel and or organizations.
