No Vodacom signal

About 3 momths ago i laid a complaint regarding the fact that we have no signal for almost a year now. Vodacom's solution was that a new tower would be installed a few 100 meters from us. Till today we have no signal. Me and my husband both is on a vodacom contract and finally decided to go to another network. Therefore im requesting Vodacom to refund us for the time that we couldnt use our phones at home. And also end our contract with them without any penalty fees. If any emergency should take place at my home I wont be able to contact any body. We just cant carry on like this anymore. If it wasnt for my wi-fi at home, I was totally blocked to get in contact with the outside world. Please call me during office hours for I dont have signal after hours.
