Poor service

So on my contract with vodacom I indicated that I want to be debited on the 21st of every month. now I got billed on the 7th of October. also i subscribed for caller identity and it was explained to me that I will be charged R9.00 to my surprise I was billed two different amount for the caller identity subscription. again after my bank account was debited with the agreed amount it still shows that i am still to be debited on the 31st of October. tried getting an explanation from vodacom 111 but I am being ignored. <br> <br> As a 10 year loyal customer i seriously did not expect such ****py service from vodacom.<br> <br> If there is any way of terminating a contract with Vodacom,with immediate effect, I would gladly like to do so
