Reported previously to Vodacom but no luck to date

We have always had excellent service from Vodacom in Newcastle, KZN but in the last few months we had poor to even no service at times. I have contacted the call centre numerous times to complain, even sent it through to their call centre email to complain but to date nothing. They contacted us once and told us that we do not have a Vodacom tower in our area which is ridiculous cause I myself have had my contract for over 15 years and never ever had this bad service from them. They are not the only service provider in our area and we have may Vodacom stalls in Newcastle. They did not even try to stop me when I said I will cancel my subscription as I am getting no service from them. There was rumors that they updated the towers a few months ago but I personally think they made it worse.
