I ordered the product by phone on Feb. 20th, 2018. I asked the sales representative (Anna) if the product would fit my 4.3 L V-6; she stated that it did. I received the item o/a Feb. 25, 2018 by UPS. Upon installation I found out that the part would not fit my vehicle. I contacted Carid by phone to tell them the part would not fit my vehicle and wanted to return the part. I spoke with Jason who checked that the part that would fit my actual engine was not available. He then did the paperwork for a return telling me that I would be receiving an E-mail with the label to return the part. The next day I called again because I had not received the E-mail and that representative (in broken English) told me that it would take 24-48 hours for the E-mail. Six days later on March 5, 2018, still no E-mail so I called again and was told a different story! I was told that they were waiting to hear from the manufacturer for a return approval. I asked to speak to a supervisor and conveniently was told that they were not available. Carid states that they have "easy returns" but I'm finding out differently. All I want is to return the Item and get my due refund. This company does not have good customer service; I believe their customer service is in India. I definitely will not make any future purchases from them.
