Poor DATA and phone service Bethulie

We in Bethulie have a huge problem with Vodacom. System is more off than on. I have to pay them monthly for my DATA but they don't supply a consistent data to me. We phone we e-mail; yes we get a reference number so long that we cannot remember it when they phone back. Promises that the technical division is looking into the problem but nothing is done. But the problem is Vodacom will not credit us for the times we cannot access our internet or phone out. Yes we the consumer always gets the worst never the best.
