Dear....you just gave them more information...they are criminals....I suggest you buy a fog horn or an air horn. When they call again answer...press 1...then blast their ears with the horn. Fight fire with fire!
I continually get these 'last calls' from cardholder services all the time. Sometimes I answer the call and sometimes I don't. I can't see caller ID very well or not at all. It appears that I can only block 30 calls with Time Warner Cable phone service. I need to be able to block at least 200 phone numbers. So much for TWC phone service!
