Query: Total joke!

I was very disappointed it would not work consistantly. Customer service was a bad joke first telling me to buy a new battery for the receiver which I did wasteing more time and money, when as expected that did not work they wanted 22+ dollars to replace my brand new collar next day air . I told them I already paid for next day delivery and would not pay again. The only positive thing I could say is lucky for me it worked when 3 deer bolted out in front of us. Returning it way too undependable.
