Legal Advice on Wrongfully Terminated Agreements

Questioner

I have an indefinite-term contract for my sports activities at a fitness club. They terminated my contract without my knowledge. I was told my behavior was arrogant and that I was acting as if it were my club. The coordinator told me this to my face. After asking for a response from the club's management, I received a registered letter two days later with the following text: Unfortunately, we've had to conclude that your behavior is unacceptable. It's quite extraordinary, as I don't know what behavior was, and there was no verbal communication, no warning, no explanation. Then they stopped responding to emails or phone calls. I've requested a proper meeting with each party three times, openly and honestly, but this was declined. My contract states a four-month notice period, or after several warnings, ultimately, termination. I haven't heard or read any reason why; it's simply that someone on the floor doesn't like me, unfortunately. I see it as business, and it must remain that way. I'm no longer allowed in, and I'm losing my clients and income because of this. My management supports me, and they're also not getting through to the other party in question. Therefore, my question to you is: what should I do now? I want to object to their unilateral decision. What's the best way to write to them, along with a penalty, so I don't lose my income?

You will need to summon the other party, with substantiated arguments, to fulfill the agreement. You will also need to set a deadline and claim damages. If you can't do this, I may be able to help.
