Order problem!

[inlinesoarer]

Hello, I ordered 95-98 Porsche 993 ignition wire set. from Miamiautopart seller!!

First of all, it was wrong order. I told the seller to cancel the order, but the seller denied and shipped out.

So, after a few days later, I opened the claim for return. 9405511699000636411037 is USPS tracking. Estimated delivery date is Aug. 23, but I didn't receive the

item!! Furthermore, seller told me a just short answer. 'We are investigating item location.' Communication with seller is so junk.

claim is closed, because the deadline was reached Aug. 26.

I need to find another way to dispute with seller (purpose: return, and refund!!)

Anybody has any ideas?
