Vodacom *****s from customers

I have had contract with Vodacom for over 20 years but truly see that this place is no longer worthy of loyalty. one of my contracts is for uncapped fiber, Simple contract of an agreed fee every month for years . It then suddenly starts to go up every month. No by alot, R20 or so rands but out of no where. I give them a call, even the consultant that took my call said it was strange as its a fibre contract, should not change amounts and will be sorted in a week as she has escalted it, it will be sorted before it goes of next month. Low and behold, nothing happens and Vodacom just bills me again at an increased amount. i called them again now and told its still pending, they will ask Lebo, who the query is laying with to give me a call back. Really now, you have to call numerous times for something they did. How many other people have they not ********** like this and not give a damn to deal with queries like this on a serious note. it down right ***** . They no longer will have support from this customer of so many years
