Vodacom Contract Cancelation POOR SERVICE

I've since requested for contract cancelation with 4 different consultant and everytime, each one confirms the contract has been canceled and I'll receive an SMS to confirm. If the SMS doesn't come through, it means the cancellation hasn't been loaded. The SMS never came through on each of those 4 - 5 times I called Vodacom. Now I cannot speak to a Consultant anymore because they've "picked up a high number of calls from yout number to Vodacom and to prevent ********** activities, we've temporarily blocked your number" How else am I supposed to call you cause I will not spend R2 a minute to that other number. This is poor service at its peak. It's disgusting. When you want to sell us contracts, you give us the best service and you dish out poor service when we want out
