Advance Auto Parts Failure to uphold Warranty Paortland, Maine

I have been using Advance Auto Parts primarily on line and then picking up in stores due to the uncertainity of getting a knowlegable counter person once in the store. I usally have no problem doing this and I always but parts with lifetime warranties whenever possible. The manager at this particular Advance Auto parts seems to have a problem with warranting items. He even stated tyhat since I didn't seem to have good luck with Advancxe Auto Parts, I should go somewhere else. I did call Advance Corporate office to get this situation resolved but still have not heard back from them in a week. Once agin, big talk and no followthrough (all mouth no trousers!)
