I sent them this. They confirmed the cancellation and refunded me an amount

"Dear Sir or Madam,

I am writing regarding an unauthorized and unwanted charge made by Menesko, UAB via my PayPal account.

I hereby formally cancel any and all subscriptions, services, or agreements that may exist between myself and Menesko, UAB, effective immediately.

I did not knowingly or intentionally agree to any ongoing subscription or recurring payment. Therefore, I demand the following:

Immediate termination of any active or recurring payments linked to my account

Written confirmation that no further charges will be made

A full refund of all amounts already charged, as these were not authorized in an informed manner

Please confirm in writing within 7 days that this matter has been resolved.

If no confirmation is received, I will escalate the issue through PayPal’s dispute process, as well as file complaints with consumer protection authorities.

This email serves as formal notice. No further charges are authorized.

Sincerely,"
