Complaint to Ebay and PayPal

Replied a complaint letter to PayPal Singapore regarding an undelivered sales transcation done in March 2009. The parcel is considered delivered by the Seller, Ebay, and PayPal when it was delivered to the wrong Zip Code that is wrong Postal Code. The smallest state of America is bigger than Singapore, and delivering the parcel to the wrong zip code is like, instead of Teban Gardens Road, it was delivered to Serangoon Gardens Road. Or instead of Penang Road in Singapore it was delivered to Penang. According to the Ebay and PayPal, the seller provided a Valid USPS tracking log, the log states that it was delivered. Yeah, anyone signed the recipient delivery order is considered Valid. Halo, I was to credit an amount of $400 into an Mr. James bank account 1234 of bank ABC, but I credited to Mr. Jones bank account 5678 of bank ABC; May I confirm to Mr. James that his bank account was credited with $400 and it’s considered transaction completed. As I had banked $400 and that it, my job is done. Like that also DaiJuBu? Or Ebay and PayPal only look into seller’s welfare? Hay Mucho!!!
