Vodacom promises

Months ago I contacted Vodacom to say that my cellphone reception was bad and it was getting worse. People cannot hear me when I phone from my house office. For business, I now use my land line. After several weeks a Vodacom operative called to find out what the problem was. I told him that my cellphone reception was bad and getting worse. He seemed surpised, but promised that the tecinical team would be in touch. Several weeks later I received a SMS to say they were looking into the matter. That was 6 weeks ago... I do not live in a remote area, I am between Stellenbosch and Paarl
