Poor network response

i did put in a complaint with call centre agent about poor network coverage. on the 01 of February Lina called getting more info about my problem. she said a field technician will call me and come to check the problem. after few days the field technician called, i explained the problem. he said he will be going at home. I called my mom,, who called vodacom subscribe in the neighbor hood who experience the same problem. they waited and he came late, around 5 and my mom was not home, he found my daughter, she said he tried to connect but couldnt, he was also struggling. he didn't call me back to give me feed back to date. my neighbor asked me about it last night as she is also struggling with network. Why am i paying for the service i dont enjoy? I pay almost R800 every month for what? I run a business and mostly use facebook for orders and advertising, sometimes i receive the notification but cannot open the page or view the order. Why should ii contunie waisting my money? I have to be outside Soshanguve to be able to connect. Please do something or terminate my contracts ASAP.
