CubeSmart complaint: Contract Illegal or Unenforceable

In March I became very ill due to mode that appeared on ceiling, coughing constantly every time having to go to storage to get online products out. When mentioned to Management, it was played down and that I was really the problem. Illegal and Unenforceable contract writing as submitted with out my knowledge about not pursuing lawsuit due to the illness without my knowledge and so was my signature added. The only thing I signed was the terns for a unit, not for any accident or issue at hand. One week later after leaving the location, after I had already moved to the new unit the contract with a different signature was sent to by email. Due to the forgy laws in N.C. and the under handed actions this management has caused, we will be leaving this location and have legal supervision already reviewing illegal contract additions added by a cube smart manager not a legal expert or lawyer barred by N.C.
