Doesn't get ANY feedback

We have been struggling with Vodacom for almost the whole year now. I have sent millions of emails asking them to help me sort out a problem on the account. They keep on Migrating the account without us giving them any permission and then the account will go up from R760 to R1200.00 pm (for example)

I am tired now begging them for answers, I also asked them if we can cancel the contract because this is getting out of hand but still no answer, they give me different people to email but still dont get any answers from them. This is for our business phone.

I use to be Vodacom on my personal phone but I changed services because of the bad service you get from Vodacom
