Ok, so I'm a student and I needed to buy a Panasonic AG-HVX200 for a production that I am shooting. I find a rather nice ebay retailer the sells it for cheap. I try to buy but paypal won't accept my bank card because it has a limit of $5000 and my purchase is for $6000. So I try an echeck. Cool. But now it says the payment will clear Oct 3. Not cool. I call the bank and they tell me I need to go to the branch of my account and ask them in person to do an increase on my daily limit. They did. So I call up retailer and tell him cancel the last transaction and sends a new invoice so I can pay him on paypal via my bank card. He says ok and away I go. Now I have my new paid invoice and I try to cancel the eCheck just to find out that I can't and no matter what I do paypal will try to withdraw $6000 for a canceled transaction on top of the actual payment of $6000 for the second invoice. I called my bank and they said because of the circumstances there is nothing they can do since the transaction hasn't occured yet for the eCheck and nothing can be done until it is returned and only then can I put a stop payment on it. UGH!
