Your agent killed my ADSL line and left the job!

On Wednesday you Telkom Tech Ashley Uys *** from Lady's Mile Exchange came to my flat to fix a slow line fault on my ADSL line number ***, he found there was a sync and authentication fault on the line, after numerous port resets, he ordered a new port which was sent and activated on the line. However on testing with 2 of my modems - a duoplus 300 and an Asus N55U and his own Telkom DLink modem, the line was syncing ADSL but refused to authenticate. At 2pm, he packed his things and told me his boss named Michael Chivell on *** asked him to abandon the work that it will be fixed at the office. He left my apartment with no internet connection since Tuesday 2pm. I have no Internet since then. I have made several calls to 10210, logged several faults to have another tech sent out to complete the work but no one has been sent up till now. I need this problem to be fixed as soon as possible bc I depend on this line for my work. The current fault ref number is: 51BWK200216. I also need to be refunded for all the day my line has been down without access. It is only fair that I am not charged for service I did not use.
