I am getting collection calls from NCO for a person that must have had my phone number in the past. When we bought our home almost 2 1/2 years ago, got the number we have now and the calls started immediately and were sometimes many times a day. Every time I have spoken with someone, have been assured the number was being removed from the system and I would get no more calls. Since I worked third shift back then, I needed my sleep and even called to get their information rectified.
