Rentoza shady business practices

Ah well here we go again. With all the negative reviews and some of my own specifically regarding locked phone issues and debit orders . Is there anything we can do legally about rentoza. With some of their business practices , how are they even still operational .Also guys please be careful this is not a rent to own business .Please read everything carefully or you will regret it like i am especially with there buyout policy. I rented a Xbox series X and after the contract tegoes urm was completed the buyout price goes up by R2000. As usual no response to my emails
