Hi my caller display has not worked since around last July, when my service was migrated from Shell to talktalk. I have checked that the problem is not my phone by taking my phone to my mother in law's house where the caller display function works okay. I reported the fault ages ago and raised a complaint but talktalk still have not fixed the fault. They have texted me many times to tell me they will contact me at a certain time, (but often they do not contact me). When they do contact me they say they will reset the line and it should be working in one or two days, and they will contact me to confirm that it is now working. But they do not contact me to see if it is working, and the caller display remains faulty. I dont understand why they are unable to fix this fault
