Poor Service

More than 20 days ago I lodged a complaint that the signal strength where I stay was poor. In fact it has deteriorated during the last three years. I was informed that a technician would contact me within 10 days. To date no technician has contacted me. I in turn have contacted their coverage dept. several times. So 2 days ago i requested the amount to cancel my contract only to receive an email today to say that I will have to wait 2 days before I could receive the information. I advised the sender of the email that I wanted the information by noon today or else I would have to take action. Low and behold as if by magic the information I wanted arrived.
