Disgusting pathetic service

We reported a fault on 02 Sep and 06 Sep and received ref nrs 690cwk020915 and 84cwk060915. escalated on 3 occasions , more ref nrs 741552 and 46556. more than a week and 6 calls later still no one has been dispatched. This is the most pathetic service and when you call the call centre they put you on hold for hours and do not return , this happened to me twice. This is most frustrating as the call centre staff above have no process and I am sure they are not being evaluated, how can you put your clients on hold for so long clearly with the hope that they will hang up Can someone please send a technician to resolve this urgently
