Bad service

On the 6 August I lodged a complaint that my cellphone signal is extremely bad and due to this I cannot even work from home and is affecting my life because of this. This signal is bad with every person that is in my house. On the 25 August a technician was suppose to come to my house but never came due to personal reasons with his car. He then again came on the 01 September to do testing and 9 days later I still have not heard any feedback. It has now been more than a month since I logged my complaint and nothing has been done about it. I am disgusted in the service of Vodacom as this in turn is affecting my way of life. Would someone please do something about it!!!!
