Query: Product and Support issues

The starter seems to work, just not on my Jeep Cherokee. After 2 phone calls and several emails to support, it was determined that the unit was bad. Got a new unit, installed and the same thing happened. The unit doesn't see a voltage increase once the vehicle is started and shuts it off. Tried to get in touch with support again...not happening.Support just stinks, you have to leave a message and hope they call back at a convient time. Email takes 2 days or better.
