Golds Gym Manager Would not renew membership because I would not apoligize to trainer who was rude east windsor, New Jersey

I was a member with Golds Gym in E. Windsor for 2 years, I went 3X a week, and every Sat. and Sun. faithfully.  One Saturday morning I was at the gym using the equipment and there was a couple with one of the trainers.  After using one piece of equipment I went to another in the facility, no one was using it, when

I got on the equipement, I was told I had to get off because the equipment by the trainer because the couple she was training was using it, I told her no one was using the equipment, so I had a right to use it, and said I pay for the use of all the equipment here at the gym.  Once I finished using this piece of equipment, I continue to use another piece of equipment that was next to the traner and couple. 

The trainer and couple both agreed in their remark to me I was a b*tch.  I told them to leave me the F---alone and continue my my work out.  When I call the Gym manager that monday, I explained what had happen, and was told they will straighten this out because if the equipment was not in use then anyone can use the equipment.  Well I was told I needed to apoligize to the trainer by the manager because that what is expected. 

I was told my membership would no longer be honor if I didn't aplogize.  I found out from one of the other trainers that this trainer had lied, so now I am no longer welcome at this gym.  I have always mind my own business, never create any problems then or now.  What ever happen to customer service.  I am seeking the name of the owner(s) I will also write to this person as well. 

Thank you
