NCS LLC They have been harrasing about a supposed over draft fee from wells fargo Texas

I have been contacted several times times by this agency they have gone as far as to contact my sister in law and my father in law looking for me. They have stated that wells fargo has put out a collection recovery for an over draft fee i had back in like 2008 or 2009, but since I was non complient they sold the file to one of their clients which they never gave me a name or anything. I contacted wells fargo and their collections departemnet both have said that my past records are clean. They gave me a phone number to a consumer report aganecy and he too stated my records were clean. After learning all this information i waited for them to call me back an relyed all this formation to them they still wanted me to pay 1500.00$ or face a judge a court. I simply said i know you guys are trying to scam me and i am not going to pay you guys anything. She kind of got nervous after i told her and stuttered a lot. One of the names is Maddie Wagner. Just like the gentleman I spoke to from the consumer report agency avoid them at all cost because they are very harrasing people and get nasty quick as soon as you tell them you will not pay
