Question Author
Thank you both for your advice ,its from bt.athome @.com so it looked genuine anyway I clicked on a link that was there and it took me to bt and it seems if its to do with making phone calls over the net ,and Ethel it was addressed to dear custumer and it had the bt logo so it looked ok I'll get the wife to ring bt she has better hearing ,,Thanks again for advice we feel happier about it now, I think its the word account that throws us oldies
all the best
