I have a BT phone which can automatically send a text message to my mobile if someone leaves a message on the answerphone. Until very recently these have been free (I think up to a certain number which was never reached). I notice that since I renewed my contract, these text messages have suddenly started appearing as charged. Have the packages changed in some way or should I complain? (I have Caller ID - free as part of the Linesaver deal - and an Anytime Calls Add-on if that helps).
