Hi.
According to Ebay rules and policies u are not allowed to threaten me, blackmail me or in any other way abuse the return policy.
I will not tolerate your preposterous accusations of fraud, your threats, your blackmails or your attempt to abuse the return policy by threatening me with negative feedback.
U are welcome to return the items if u didn't like them (although this is a mere case of buyer's remorse and nothing more).
However u should return the items in their original condition at your expense and I will gladly refund the value of the items and the original shipping as soon as I receive them.
Any further harassment and malicious activity (such as threats and/or blackmails) will be reported to Ebay.
U are welcome to open a case with Ebay if u don't agree with the return policy.
