Order still executing,line installed not active

After my complaint last week Telkom helped very quick by switching my adsl, now after its been switched the order still shows executing after it has been done on the 4/06/2015 . calling 10210 doesn't help they say back office must confirm the installation. Now I am paying already my ISP for the service , as I was consulted the line is ready and still nothing on Telkom's side is right!!!!!So how do one get hold of the back office to just confirm installation????
