F.U.L.K Inc Lawrence Dixson Pushy kid accosted, coerced, fraud end me while in duress Lawton Oklahoma

Was shopping at SAMs club with three kids, two have special needs.  College kid came up saying "buy magazines for deployed soldiers.  Said you get your money returned after three days.  My newborn was vomiting, my autistic three year old melting down.  He wouldn't leave.  Said write this check out to me, write this check out to me.  i was scared, Lawton is not a safe city, and he was very pushy.  I wrote a check, googled company once I got in my van and locked the doors.  No company info at all.  So I placed a stop payment.  Now a third party check cashing company is taking legal action against me.  I'm not paying.  I thought the guy was going to hurt me or my kids.  No way.  I will sue the pants off Mr. Dixson and F.U.L.K Inc
