VODACOM= PATHETIC!!

I am battling with Vodacom's useless service. I paid my phone contracts by Dt Order which Vodacom stuffed up by deducting monies monthly as they wish! This resulted in deducting thousands of Rand causing me to stop my Dt Order. I did not pay for months till these access amounts were depleted. I must now start to pay again by EFT so that I have contol over my accounts. On more than one occasion I send emails to cuistomercare@ vodacom.co.za asking someone to phone me in order to get the correct detail to be able to do an EFT monthly, but Vodacom refuse to and send an automated response to me by email saying I must use their Tobi **** that does not work!! I informed Vodacom that I won't pay my bill because they refuse to help me! They promised 7 months ago to fix my Vodacom signal as I cannot make or receive calls 80% of the time. Nothing happedend. Same as with their Vodapay app which were reset 4 times at my Vodacom service provider, but I still can not read my air and data time! PATHETIC firm!!
