Repossesion of rentals

I have 2 contracts with teljoy one for a fridge and one for the ps4 i have not skipped a payment on the fridge ever but the pa4 payments are in arrears. NOW THEY WANT TO TAKE BACK THE PS4 AND THE FRIDGE. even though the fridge is paid for every month as agreed. The ps4 is a seperate agreement. How can they take both back??? Surely that isnt fair. I hate when companies just do what they want when they feel like it
