Business Internet not working after numerous calls

Our Internet has been giving problems since Monday 11th February we have made numerous calls to Telkom they had promise us that someone will be looking at the problem till date it still hasn't been fixed upon calling them Cacious Ledwaba informed us a technician was sent out on Friday but no one pitched at our offices on Friday when contacting them say the person must have gone to the exchange but still no internet connection on our side however and no one calls to inform us how far they are or anything I mean this is seriously bad for our business as we relay heavily on our internet for most of our business.
