Fraudulent behaviour on my bank account

[monimarz]

On July 9th I received notification from my bank that a transaction was made from: ynapcorpora for 405.00 CAD. When I inquired about the amount, as I had made no purchases on this day, the bank informed me it came from PayPal. I immediately reviewed my PayPal account and no electronic footprint could be found. When I asked the bank who the code name came from, they stated it lined up with NetaPorter website. I contacted NetaPorter as well to report this. The strange part of it is that they took $405 out of my account and then returned it immediately? I simply cannot make heads or tails of where this transaction came from?

I HAVE NEVER HEARD OF THIS PERSON BUT FOUND IT STRANGE THAT THE SAME TIME IT WAS PUT IN MY PAYPAL ACCOUNT HE CALLED AND SAID THAT HE DID IT ...NOW I HAVE A CASE AGAINST ME FOR THE MONEY-- TRIED TO EXPLAIN THE SITUATION TO 2 REPRESENTATIVES WHO DID NOT SPEAK ENGLISH AND REPEATEDLY SAID THAT THIS MONEY IS MY RESPONSIBLITY TO REPAY... I DO NOT HAVE THAT KIND OF MONEY AND I DO NOT HAVE ANY IDEA WHO THIS PERSON IS BUT HAVE BEEN NOW SCAMMED OUT OF LOTS AND LOTS OF MONEY FROM THE SCAMMER WHO HAD ME USE THE MONEY FOR HIS BENEFIT.  WHAT CAN I DO AT THIS POINT??  I WAS SCAMMED BY EVERYONE INVOLVED AND I AM THE INNOCENT PARTY.  NOW WHAT??
