Have received several calls from this number (caller id shows 44-207-400-3462). I did not answer the call this time and they did not leave a message. Previous calls have been from "Credit Card Services" which I have searched the internet for - all to no avail. THe last time I answered this call pressed the number to speak with a representative and asked to have my name removed (as I'd done previously) as I was on the do not call list - the woman on the other end was very nasty. I would like to know how to stop these calls.
