Need a solution to get a cashapp but im not in US or UK

I am using someone else’s cashapp as a payment gateway for my business. As I’m not in USA cashapp sometimes asks for verification and those cashapps i am using belongs to someone else and i bought em from them.
Now when i contact them back for verification they usually connect their bank and cashout everything from it and just block me.
Do amyone have a solution to this i will really appriciate it.
