Vodacom shame

I have had endless trouble with Vodacom after being a customer for many years. I took out an LTE package that I cancelled the very next day, which they never cancelled and billed me R2200.00 which I reversed, only to find out they added my cell contract amount in there and then suspended my cell service. I went to the vodacom4u at the vaal mall, only to be shunned away as I am not the account holder and the staff and manager were not very forthcoming in trying to help me. The service was the worst I have recieved since moving here.

I am thinking of cancelling my contract with them
