ADSL line down for 4 Days!

Service call 191CWK190216 logged Friday 19 February 10h25, this is a BUSINESS ACCOUNT. Escalated on Monday (826783) and to date NO response from a technician. Every time I call, the excuse is that they are aware of the problem, remote monitoring was done but the problem is with the line, they will assign a technician shortly. When I inquired this morning, I was told that there is a shortage of technicians, and the escalation is still in the queue to be assigned. So, to date no effort has been made to rectify the problem. We are loosing customers due to this! Are we going to get a discount on our next invoice for lack of service? Pathetic!
