Telkom lack of commitment to customers

My landlord and i are sharing a DSL data line, it been down for the last two week, problem has been reported multiple time ( case numbes ***2, every time we report the problem all they can say is " we will send someone to attend the problem with in 48 hours". Its been two weeks since the first report of the problem, all we got was an sms to say the problem is fixed but still we have no internet access.
