Product: Money transfer, virtual currency, or money service

The sellers filed a chargeback claiming fraudulent they're buyers. I'm the buyer who didn't receive any service from their scam online app. They refunded me, and PayPal held my funds {$4400.00}. I was given different information through different virtual agents through PayPal. I follow every direction according to your customer service people through text messaging. Each time we would have a different representative in different departments. Even themselves said that they are not equipped to handle and I'm rerouted multiple times each time I try to contact them. I notify the sellers to contact PayPal to verify that the funds are mine were the. I notified the sellers to contact PayPal to verify that the funds are mine for the refund. In which I did get all of the email correspondence to PayPal proving that the funds or confirm buy them for my refund of their failed non-working app. Then I got any email from PayPal telling me that they are filing a chargeback claiming that they are buyers and I didn't get any items and the item was defective. 
Paypal should ask them to send a picture of what did they order? Where is the receipt what did they order? Show us the defective item? 
Instead of asking them the most obvious questions Paypal responded to me that I am the seller and they are still the buyer and they didn't get their items and then just recently they revise their claim that they have a defective item. I do not know what kind of business PayPal is running but I did a lot of research on them. They have no practices to be very irresponsible responsible. I had to hire an attorney to write them a letter to let them know that I am the buyer and the seller are the ones filing / claiming fraudulent To Paypal to get the charge back refund it to them! Up until today Paypal still can not distinguish between buyer and seller? That tells me that whoever is sitting in the back of that desk is not trained well and not able to understand my concerns. 
Paypal keeps sending me emails Buyer didn't receive their items and now it's defective and for that reason they will refund them. I sent them over 20 pages of receipts, attorney letter, email correspondence, my buyer receipts, letting them know that the buyers are fraudulently trying get a refund back from me, when the funds rightfully are mine. 
Paypal community page has shocking and disturbing complaints and they are so similar to mine. I am not a regular user of PayPal therefore I am not familiar with how these people try to do you chargebacks without Paypal having to protect me as I'm the BUYER! They didn't allow me to appeal because they keep telling me that the buyer has defective item! If that is the case why don't Paypal ask them to show proof receipts? Address where did they order for me if I'm the seller? What did they order? Send a picture? Showed a defective item? 
I don't have to work at Paypal but I am a XXXX  trying to build a XXXX business with my daughter. And the real sellers sold XXXX followers coins, in which their app fail to give us the followers paid for. So they had 100 % moneyback guarantee so they refunded to PayPal and my funds were being held by PayPal. Then for some scam reason they are now claiming that they are the buyer and they have suffered defective item and their first initial story is that they didn't receive any item. Paypal should be alert it and see the red flag didn't receive an item. Paypal should be alert it and see the red flag didn't receive an item. Now their saying The item is defective The item is defective. It makes no sense if you didn't receive an item how can I be defective!! In addition they have my credit card information in my address information because I purchased from them, so I'M very concerned that I'm a victim of identity theft, scams, and paypal has done nothing to investigate them. Not only that, each message from different representatives are always different! Nobody @ Paypal seem to be The seller fraudulently filed as buyers and filed a fraudulent claim. Here are the e-mails proving that I am the buyer who purchased a service from the seller. I did not any services rendered. I was being refunded b seller. Here is the proof and e-mail correspondence between me and the sellers that shows that I am the buyer who purchased XXXX followers from the seller and they were refunding me. 
Instead of refunding me the file as buyers fraudulently to get a charge back from PayPal. 
I hope the PayPal please shut their account down as they have filed several fraudulent charge backs as buyers with no proof. Please help me to get my refund back as I do not know how Paypal can let them get away with fraud claim. I am adding additional information here as the resolution area does not have a place to add extra information. I just found this out recently. I need the help to get my refunds back.
