Order by mistake AGAIN

So I get up this morning and long in, and see that I had a $55 order. Wow nice, and then there was the message,
"The buyer has requested mutual cancellation."

Wow, happened again. I have read somewhere in the forum that it is actually possible to order multiple times
by mistake because the iPhone messed up or something, but I am guessing that it rare.
This is the exact message the buyer sent me:

I ordered by mistake. you sympathize settle my money refund . thanks

Not really sure what the person is trying to say because of the broken grammar, but I am guessing
it's something along the line of sorry, I hope you understand, gimme back my money. :P

I clicked decline just for the heck of it, asking him/her to kindly explain how he/she can possibly order 11 gigs by mistake.
What? I'm acting like a 5 year-old? Heck yeah!! :D

Well, I will cancel the order eventually. :P
