I sold a set of wheels online. Buyer was happy with it, no complaint at all. Fedex with tracking on record. Out of nowhere Paypal locked my funds and said they have to "investigate it".
Investigation result: "We'll keep your money for 180 days interest free. Thanks."
Both the buyer and I had no idea what the hack was happening. Buyer never filed any complaint with Paypal or his credit card company.
I called Paypal a few times, they said the computer system randomly found my transaction as "high risk" and they'll have to lock it for 180 days JUST IN CASE the buyer files a complaint.
Yes, you heard that right. Paypal was trying to protect themselves from a loss "just in case" the buyer wasn't happy with the item.
In this case, my buyer was very happy with my item, and they kept my money for no reason at all "just in case" anyways.
The girl on the phone found no reason why Paypal would need to hold my money. "Sorry, that's how we do business".
