Query: Battery dies with every use.

I bought several extra batteries thinking this would last me at least a year, maybe two. Nope. Lasted me less than a month! I rarely put the collar on my dog for more than 1 hour and never more than 2 hours. Each time, I take it off my dog, I make sure to turn the battery to the off position. And each time, I go to turn it back on and test it, it no longer works. It isn't the batteries because I have tried several. And it isn't the way I am turning it off, because I have removed the entire battery in between wears. This is probably defective, but they want me to wait and keep trying it. Ugh!
