I am on flext 25 and have used about a quarter of my allowance this month and we are well over three quarters of the way into my billing cycle.
I take care to call only UK landlines and mobiles, no 0845's, 0870's 0800's or others - so you can imagine my surprise to see an unbilled amount of ?1.28 on the bill as follows:
16/07/06 00:15 3000 Standard Call 00:00:01 ?1.277
What is this? Looks very much like a scam to me. Am holding for T-Mobile to clarify atm but thought I would see if anyone else has come across it.
