Complain about RAIN COMPANY

Rain company is a ****. I started using their service in 2023. But suddenly when I requested to unsubscribe I was the told that I owe them from November 2025 meanwhile I did payed for November 2025. I was told it's not a contract but month to mont services. I'm shocked that I have been told that I signed a contract. But when I requested the proof of written and signed contract that they claim I signed including the proof of the last time I I used thei services they failedd to produce those documents. But they still continuing intimidating and harassing me on a daily basis that I'm oweing them. Please help me get RAIN COMPANY off my back. It is not fair what they are doing to me honestly
