[Weird] Paypal Transaction ID Mismatch...

The client sent me the money, and I can clearly see it on my paypal balance.

However, when I ask him to provide the transaction ID, he provided a
completely different ID, like this kind of different:

His:
ScNsEPkohl9seEeCfU9U
Mine:
lGE6SrAj7w5ZLzyRHQLg

(Note: these are just random passwords I generated)

Have you ever seen this kind of stuff happen?

pfft i just ask for the email they paid with, cause for some reason the trans ID never match lol.

so from the jump i always jsut ask for the email they paid with.
