Auto Computer Exchange Inc ECM-To Go Stole My Money and Shipped Me JUNK four times, will not refund $ Davie, Florida

I decided to purchase an ECM (Electronic Control Module) for my car from this company because they self describe themselves as "The ECM Good Guys", American owned & operated family business since 1997.

On the phone they were very confident that their ECM would solve my problem (jerkey transmission).  They said and their website states "We eliminate the need for you to take your vehicle to the dealership.  Our researchers and technicians have made it possible for us to handle all programming, flashing, updating, and/or relearning before we ship your part.  When you get your new part, all you will have to do is plug it in and you are back on the road."

The first ECM they shipped me was smashed with broken pins (where you would plug it into the car) but packed in a box that was not crushed or damaged.  So they placed a broken, crushed ECM into a box and shipped it to me.  I called them to report this - they requested I take pictures of the ECM (I had to drive 1 1/2 hours round trip to take pictures for them) and email them so they could get a new one out to me ASAP.

The 2nd ECM they sent would not start my car.  I called, they shipped another one.
The 3rd ECM they sent would not start my car.  I called, I spoke with the "manager" - he informed me I would need to take the car to a Ford Dealer and have the computer flashed or a locksmith.

I went again 1 and 1/2 hours to get the car and the 2 ECMs they shipped, took the car to a Ford Dealer near my home, the Ford Dealer worked with Auto Computer Exchange on the phone, could not get either computer to work.

In the meantime, they shipped a 4th computer to my mechanic???  I'm not even sure why, I was not expecting another computer.

I spoke with them about a refund, they agreed when I return the units they will issue a refund.  I shipped back their junk, had UPS signatures that they received it.  Called for my refund, at that point they said they would give me a store credit.  I'm an individual girl, not an Auto Shop, I need a store credit about as bad as I need a case of plutonium.....  They insist I will never get my money back from them and want me to send them the original ECM that actually runs my car....

Now, who in their right mind would send these crooks, incompetent, degenerate LIARs the one computer that actually runs my car?

DO NOT DO BUSINESS WITH THESE PEOPLE, They do not care about helping anyone, and they have no shame over the way they LIE and ROB people.  Between buying this unit, paying my mechanic, paying the Ford Dealer I am in about $700, nice huh?  Nothing is resolved, my car still jerks :o(
