Waiting 5 days for response

I logged a fault (126CTK211115) on Saturday 21/11/2015.<br> <br> On 23/11/2015 a technician called and asked if I was available for him to check my line, but 4pm was too late for him. I indicated that someone would be home from 12pm from the next day, and he agreed to come then. <br> <br> However, it is now 3 days later, and no one has made any further effort to sort out my phone line.<br> <br> Please follow-up on this fault as I have been waiting 5 days for my line to be fixed.
