Very bad data signals in Heilbron

My wife phone Vodacom several times and complained about problems with our data signals. She receives a respond that she is the only one that complained. After a posting on Facebook more than a hundred users contacted her, complaining about the same thing. Last week, a representative of Vodacom came to see her. The list was given to him. He run several test, confirming that there is a problem in this area. He told us he will contact us again on Friday last week. Today is Tuesday. The signals can't be worst. I need to do my work and need a good data connection. There is also students in this area, using data for exams. Myself end-up with a re-examination because of a slow data connection costing me additional fees and study time. Vodacom you services is really bad ! I can't understand, if you can't provide a service in Heilbron why did you in the first time sold your services to us. We can't used it. Save us the frustration, pack your equipment and move out of town if you can't provide any services..
