Running into the same issue as multiple other PayPal users with the company called UAB kilo grupe. It set up a monthly recurring charge of $37, which I never subscribed to or authorized. PayPal resolution center got back to me twice saying the transaction in question was NOT unauthorized and the case is closed.
UAB kilo grupe (based in Lithuania) is definitely a scam. They hack PayPal accounts and create subscription payments usually $33-$37, from what I can tell from other users commenting, and PayPal refuses to refund because they can't get the money back.
What a nightmare. Just got off the phone with a PayPal specialist and made him do a Google search of the company, to make sure he sees multiple people running into the same issue. Unreal.
