Breeder network another let down, Internet

picked up our so called mastiff at the airport were he was left in a hot aircraft hanger with a couple of other dogs and of coarse there was no papers but the air shipping papers. we went to the vet from the airport because they said to get the warranty we had to see a vet within 24 hrs after a bunch of phone calls and a fax we found out what shots were done and moved on. now just over a year later and a bunch of phone calls later there is no way to get in touch with them and I have a male old english mastiff about 100 lbs with no papers and a lifetime warranty that is no good. now don't get me wrong we love our baby and would not trade him for anything but there has to be something they can do to people like this!!!!
