VODACOM SERVICE? NO SERVICE!!

I have never in my life experienced such bad service from any service provider. I have tried phoning Vodacom cancellations department, but I simply cannot make a phone call!! there is just never signal and the moment that there is any signal to phone the call gets cut!!! I have been trying to cancel two of my contracts that I simply just don't use anymore!! this is costing me unnecessary cost for something that I can't even use. Can Vodacom please assist me in doing my cancellations via email?

And then I also have another huge issue!!! I did an upgrade om my number and my wife's number, I asked the lady that assisted us over the phone to please remove the current VAS services that we had, the upgrades are now done but the VAS services are still on our account, and this is costing us now more!!!

Can someone please do something to make it easier for the consumer?

I expect Vodacom to assist in correcting this asap!!??
