National Credit Systems of XXXX XXXX at XXXX is harassing me for {$2700.00} ( ref # XXXX ) for an unpaid lease at apartment XXXX at XXXX XXXX XXXX, managed by XXXX XXXX dated XXXX/XXXX/XXXX. I never signed a co tenant lease with XXXX. I signed a tenant referral for a relative in XXXX for apartment XXXX for XXXX XXXX, which the lease was completed in XXXX. The relative moved to a larger apartment and signed a new lease which I was not needed as a reference. This was also a low income HUD building. A new management took over the building named XXXX that hired National Credit Systems to harass me due to ill standings with my relative.
