Disgusting Service for Company Telephone Line

I have repeatedly reported my business line out of order since July 2015. I get feed back that the problem is being resolved. So far I have had 2 technicians come to the premises and have proven that it is not my telephone but a fault in the line. The last technician came, tested and left for about 2 hours, came back and told me that it was the underground cabling! I have been without a telephone now for 3 months and will object to paying the line fees for this period. Why can they not attend to the problem and not put it on the back burner. I have asked for escalation on this with ref no 1201OMNLTV2 given to us on 01/09/15. The original fault report ref no 340CRZ190815. This is now an urgent matter now as we have no landline at all and using my cell phone is turning out to be very expensive. Hoping that this matter will be resolved a.s.a.p. with competent staff.<br> <br>
