Global Automotive Bogus Life time warranty , Internet

I purchased a electric fuel pump for my jeep on Ebay. The pump failed four mounths later. Due to the "life time warranty" I contacted them. I received a return form, and I filled it out. I mailed the defective pump to them Priority mail (cost me $15.00). After almost one month, I called them to ask where's the replacement pump? They would not discuss the matter over the phone. I was told to email them. I received an email with a form letter declineing to honer the warranty. I am a certified mechanic for N.Y.C. transit surface division. I do all of my own repairs. They claimed fuel contamination, plugged strainer, no proof of professional instalation. None of their reasons were founded! Do NOT waste your money here! They do not honer the "Life time Warranty"!
