Review on Cardone Select 13 2352 Master Cylinder by John Clark

Installed on my truck on September 6, 2019 and noticed a leak under the front reservoir bushing for the first few weeks and then early December while sitting in the car, my pedal suddenly fell on the floor and my brake light came on and I had no brake pedal at all. I had to apply the parking brake to keep the car stationary. I want a refund and based on the reviews for this product, it should be removed from Revain. I can't figure out how to contact the seller.
