Break in connection

Since 08/09/2017 until to today, I had no internet access. Each time when I call, I am told the same thing everytime,"there is a break in connection". Its not even been a full 2 months, and there is already issues. On top of it all, Telkom wants to bill me for the repairs and I dont even have a cooking clue whats goung on. According to me, this is also in breach of the agreement. Please advise me if I can cancel? Looks like i am wasting my rime and money.
