Ha ha, that is a new one

Buyer: "I mistakenly clicked on the payment button, I do not need this product, could you return the money to me!"
Seller: "Alright [...] appreciated if you tell us why you mistakenly paid for the item and then cancelled."
Buyer: "my phone fell from my hands during the fall I accidentally pressed the button with my hand."

Oh dear. Did the buyer's phone fall several times? Once when s/he hit and once when payment method was selected, again with the login to PayPal, and finally the confirmation of payment?

Ouch (for the phone).

As a long time seller I've had plenty of these lame excuses. However I did once almost 'pocket buy' something on eBay. I was one click away from purchase (but making payment is another thing).

I personally wish there was a way to convey to buyers that I don't care how / why the purchase was made, and / or why they want to cancel, as it's completely irrelevant to me - at best convoluted excuses are amusing, at worst they're lame and obviously a lie so just makes the buyer look bad. (i.e. don't send me excuses or reasons, just send me the request to cancel, and it shall be done....as long as the purchases hasn't already been posted). 

Ouch . Sounds like the last time they fell they hit their head.
