Bond Batteries

Bought a battery from this them. Doesn't work. Doesn't keep its charge. I paid $40 to have them test it and then tell me it's fine. The RACV won't charge my battery because they have stated the battery is stuffed. My mechanic and auto-electrician both say the same. Now it's off to court to get my money back. My car's now stuck in the garage as it won't start. Useless 2 year year warranty-where is it?
