I have being calling mutichoice from Friday

I have being calling mutichoice from Friday. I have spend morethan R100 of airtime because of their poor service I was told to keep on holding for more than 30minutes. Even now I recharge with R70 it is also gone because they said hold and hold. The truth is they had a very very bad service. Soon they will lose all their customers. They overcharged me I call them still no help. This is rude and poor customer service. I need them to call me now and fix this *******. Thanx
