Refund - I won a dispute with the seller and they only refunded 1 installment out of 5

Hello, I won the dispute with the seller, but the goods were purchased for 5 installments and only 1 was returned to me. Do I have to create a new case for each installment? I hope not. 2 out of 5 no longer have buyer protection. Shouldn't I be refunded the full amount I paid and requested? 1st payment 262.50 USD, another 3 payments (105 USD) and the last 5th payment including shipping (150 USD - this one was returned to me, but the full amount of 727.50 USD could not be requested because it was more than this 150 USD) in total 727.50 USD. I can't contact support, so I'm trying to ask here as well. Thank you

If the 5 payments were an agreement between you and the seller and there are 5 transactions in your paypal account then you would probably have to open a dispute for each one.
