In the midst of a family crisis last night I phoned my mobile with the house phone to try and find it. I pick up my house phone today to see that on the screen is a time of 21 hours and it was still active with the call to my mobile. Thing is, I cut the call on my mobile straight after I found it. Also, I am sure I never actually answered it at any point, I just had to hear it ring. In the time between then and now I have used my mobile to call other people so I know it cannot have been connected to a call with my housephone. Am I going to be charged for this?
