Telkom ADSL Line not installed after booking 4 x

I requested a new telkom adsl line to be installed. I have been given 4 installation dates between 25th May and 2July. Not once have they pitched or called to cancel/reschedule. I have always followed up a day or two later and get given a new installation date with no show from Technicians. I have sent 2 emails to escalation center and got an automated response but nothing further. I have called several times and tried to get a escalation ref number to no avail. I have been into store at Lakeside mall and was given a new installation date and assured all technical difficulties were resolved and line would definitely be installed. As I stand i do not have an installation date or way forward.<br> My order number is ***
