BAD TECHNICAL SERVICE

We Have a problem with our ADSL line. As from Dec 2015 and is still not sorted out!!!! It takes about 3 weeks after Fault is reported when anybody takes note of the call. Then telkom phoned about 3 x times to make sure you still have a problem then a technical person comes does something and said see how this goes.. After a few hours our problem is still there.Then we have to start this whole process over again.The last two times Telkom just decides that the problem is solved with out coming to our property just send a sms saying the problem is solved???<br> Not one of the technical guys went out side to test our wiring outside!!!! PLEASE LET ME KNOW WHAT TO DO TO RESOLVE THIS PROBLEM !! My Husband works from home but our internet is on and off the whole day !!
