Unresolved issues for the past 5 months

I have not been receiving stms for the past 5 months and I ve brought this matter to Vodacom"s attention on monthly basis every time when i need to pay my account. After speaking to so many agents and being dragged from one department to the other,I haven't found any joy. Now they r billing me R100 handling fee which their agents can't seem to tie it up. I have been with vodacom since 2002,due to the inconvenience of most of the staff and very bad customer service,i guess it's about time to consider offers from their competition.
