ECCPPAutoParts review: Either refund me my money for both or send me a new one or both.

I purchased a turbocharger from Amazon in November and they were the seller for the part and it went out a month later then I brought another one in December on Amazon and they were also the same seller of the part. It went out within five months now I have to buy another one. I called Amazon and they gave me information to the seller but I couldn't get ahold of anyone. I called the number they gave me which was [protected] and it just go to a voicemail. I left several messages I even sent a email and got no response. I came into contact with Amazon and they said they couldn't help because they were not the seller. I don't know what else to do can you please help. I want a refund of my money for both turbochargers that I purchased. I also would like to see if they could send me a new part or purchase one for me.
