ISP

I have been with out Internet for about a month, first we were told the exchange had a problem, but according to Telkom I still managed to use all my 10 gig of data, that was by the 19th September, I bought 1 gig and that was finish in a few hours, I do not down load any music or movies. 1st October I got 10 gig more, I only had internet for 1 hour a day for 3 days and that was finished, I can't get anyone at Telkom to help me, I have been shoved from department to department with no help, I phoned every day for a week, I then started sending messages on their facebook page, still no joy, the reply I keep getting is \Hi
