I am sorry to hear your telephone feature is not working. Just for clarification, please can you confirm do you mean 1471 as in finding out who has called you? Or do you mean the withholding your number feature?
Thanks for confirming. I would like to take a closer look at this for you. I am going to send you a private message to enable me to do so. Please look out for the purple envelope in the top right of your screen.
