Vodacom pathetic service

Vodacom pathetic service -- it took me 2 days to get through to Vodacom and finally today after the phone was cut of after 30min the call centre agent picked up the phone - i want to cancel my contract to go onto a prepaid contract the agent did not want to accept this as NOW suddenly i have been a great client of them (from 1997) and he can offer me a better contract from R780/month to R599/month what a cheek - my instruction to him was to cancel my contract when i said NO he asked to hold on for a better package and then the phone cut off - i do not have the luxury of time to hold on for another 30min... To put the cherry on the cake Vodacom decided to deduct R1,700 in access from my invoice payable of my account for June battling to get my contract cancelled HOW do you think it is going to go with getting my money back... Vodacom is dishonest and manipulates us....
