Faulty Extension

I reported my land line on the 16th November - Ref no: 98CNK161115 and even though a technician came out to repair it, the extension in my room is still not working. I reported this via sms, made numerous phone calls to the call centre where I sometimes had to hold on for over an hour - this being very frustrating as I have to phone from my portable phone where I eventually have to call back as the battery runs flat! When I tried to report it on line it wouldn't be accepted as it had already been logged on the system!! The last person I spoke to was Abraham last week who gave me a new Reference, 79707 and told me that I would receive a sms which I still haven't got! I pay for this extension so expect of it to be fixed! <br> Please regard this as urgent. <br> <br> Erika Sissison
