What SAM1911 said. Yep. Had the same problem here too. Also most clerks don't know squat except for what they read on Internet forums, only interested in making a sale. I cured the problem and opened my own home business and do special orders and repairs in a converted garage. But not everyone can do that. I would take SAM1911's advice. Just remember, you get better results if you have the gift of gab and the ability to to someone to go to hell and have them look forward to doing it.
