Orangetheory Fitness St. Petersburg

I left the gym- the continuously call me. Try to authorize my credit card and contact me via email.
Left gym. No longer member. Claiming I need to pay my debt. The gym is month to month after several months of continuous phone calls. Online email threats. I was told they will "ruin my credit" this business is bonkers. It's pay as you go. They want me to pay for services I've never received.
