No service and no technician

<p>We reported a fault on our adsl line (Ref 605CTK170117) on Friday 13 January because the line has no service , then our landline also went dead and we reported it Thursday 19 January (Ref 411CTZ190117). A technician came on Saturday 14 January, but he failed to correctly diagnose or fix the problem, and said he'd be back the next day or Monday, but no one has come again. I work from home and internet is vital and is costing a lot to be without it. Please can it be sorted urgently! </p>
