keeps calling my job, and I have told them to proved to me I owe a bill, whatever it may be and they just keep telling me they are taking me to mcourt and a sheriff will come to my job! At first they scared me and I almost gave them my credit card number..but I thought betterr of doing that. They have yet to prove to me whatever I owe. they have been advised to quit calling me at work, but they keep on.
