A XXXX XXXX XXXX is calling / harassing my wife, me, and now my wife 's mother. He is calling on behalf of Feldman & Stern, LLC out of Florida, which I believe is a company created for just these types of scam opportunities. He is telling me that I have 24 hours to pay this debt that we have never heard of. Apparently the $ 100+ debt is from their client, XXXX XXXX, which we have n't been members of for about 5 years now. We contacted XXXX XXXX and are hoping they take this to the top. This debt collector email us a letter which we asked for and it look so un-professional with many errors. FAKE ... The address listed is XXXX XXXX XXXX XXXX XXXX XXXX XXXX XXXX FL. XXXX which is different than the address for this LLC on the secretary of state 's website for Florida. Anyway ... they gave a phone number which is XXXX
