TELKOM IS RIPPING ME OFF.

i have a R400 contract with Telkom. I pay R500 monthly.of late Telkom is now charging over R1200 and every month suspend my line despite the payments made. When they suspend my line, they charge me an extra R190 a month. Last Month they made me pay R1135 which I did. This month they say my payment was short of R533 which was never mentioned last month and have again suspended my line. They didnt even have a courtesy to call me and discuss this with me.that in turn means I have to again pay another suspension fee. Im soooo ****ed off with this company. To think I used to work for them. MXM
