Anyone here missing incoming calls, I have been missing calls quite a lot and today is the worst of all days. I missed 2 calls from Doctor as when I rang them they said they could not get through to me, then I got 4 others to ring my number over a few hours and although the phone is ringing on their handsets mine is getting nothing in, not even a missed call or voice mail. Then another time the phone will ring and seems to work perfect. Then again nothing when the same phone rings me back again. It's not service or credit it's like random lock out of calls
