I ordered two Pet Safe collars, rec'd 2 which did not work Called them, returned for replacements. Rec'd one replacement, called again for the other replacement, they stated they only rec'd 1 collar. After arguing with them, they refunded for one collar. The replacement we rec'd? Did not work after less than 2weeks. Called them to return, They reported that we were refunded for two. NO! Now they have to check and call me back. Let's see if they do. I contacted Pet Safe and they were not interested in intervening in this problem I figured since this company is representing the Pet Safe name they would have something to say about it.
