Autozone Witportjie gives **** warranty

Autozone sold me a battery and gave me an 18 month warranty. After 8 months their battery couldn't hold a charge. I took it there twice and they refused to honour their warranty. I took the battery to battery clinic Krugersdorp and they tested the battery and found that it couldn't hold a charge. They sold me a battery and gave me a report on the battery that autozone Witportjie refused to replace. Autozone Witportjie gave me a **** warranty! They are not to be trusted.
