Can I change my positive feedback to negative after finding out it's fraudulent?

[transfixiated]

I bought an item, received it, it appeared good so I left positive feedback.  Now I believe the item is fake.  Can I change my feedback to negative now?

Think i would try and confirm suspicions and then contact seller prior to altering feedback. How long ago , can open disputes for 45 days.

Cannot change a positive but can leave a follow up to the feedback, Click on feedback forum on left this page. Others read so calm and factual is best.

Start with contacting the seller and trying to resolve the problem. The simplest resolution is returning the item for a full refund. The seller has the option of also refunding your return shipping if he agrees with your opinion. Use Confirmed Delivery, which is Expedited Parcel in North America.

If the seller is not helpful, you can go to a Paypal Dispute "Item Not As Described".  You have only 45 days from the end of the listing for this.

You can leave Responses to feedback, both yours and the seller's, indefinitely.

If more time has passed than 45 days, you can go to your credit card for a chargeback.
