Amazon closed my account?

Amazon closed my account for returns. Meanwhile, I had purchased an iPhone for $300 which I returned back unused as I had purchased another one on craigslist but the iphone was shipped back in the morning while they closed my account in the evening so the iphone is still on its way back to them & im worried about my refund now wondering if their return label with the RMA is automatically void or not? I had also sent back a return worth of $600 which arrived to them on Nov. 24 and today is December 6 & while my account was opened all that time, I was still waiting for the refund & now that it closed how would they process the returns for me so i can get my proper refunds? I have the tracking #s & evidence of the sent items. Will I still be able to get an automatic refund confirmation email from amazon when they process my return even with a closed account? im trying to figure out if all orders are voided when they close accounts or not so? What can I do to get back my refunds that they have the stuff?
