Disgusting service from Vodacom

I called Vodacom and asked them to do a number change on my contract. That was Saturday the 13th and still waiting for them even now. I can't receive calls and when l text people it shows the old number. I called them numerous times and no assistance. First it was attended by Thembinkosi Ngcobo, ***, vodacomcomplaints@vodacom and now they are all ignoring me. What makes it worse is now my number is barred and can't contact them. This is very bad service from Vodacom and l want everyone to know how we are being treated and we have contracts with them. To top it all off l received and email that tells me that they have set up a debit order of R150 for the number change, imagine these people.
