Just received a letter from the manufacturer of the exhaust diesel cap. This seller "Gorge" is running a triangulation scam through the Walmart refund policy. The seller claims a refund in the buyers name, sends a cheap part to the manufacturer to receive a full refund. The manufacturer is out the refund and the part. Talked with the manufacturer but it appears the only way to stop a triangulation is fo Walmart to introduce a verification program similar to Alibaba.
