Planet Fitness

I was handled extremely rudely at the front desk after I had already been there twice wearing cotton stretch jeans which I had worn all through my rehab for triple bypass and for almost 2 years at LA fitness I was told that I could not enter because of my jeans I was told by the manager that the grommets would affect their machines I responded that these pants had no grommets and that they were stretch pants. they would not let me in past the desk. What part of pants touch a tread mill? I have contacted both online and the local where no one even answers the phone or from online regarding the cancellation of my membership. Also I am allergic to nylon & most synthetic fibers.
