Account suspended, no reason

I have a telkom phone line in order to access dsl through a better company. Have been using my internet for 8 months and all of the sudden Telkom suspends my account and rejects my debit order. Now I dont have access because once again Telkom has taken it upon themselves to take a perfectly happy and diligently paying customer and cause problems for no reason other than to lose clients. Worst company in SA if not the world, stay away.
