they were mailing us replacement batteries for our fencing system. Our dog passed away & we called and asked them to cancel our account & discontinue sending us batteries and they agreed. 6 months later and they are STILL sending us batteries for the collar that we don't have anymore, and every time we receive one it reminds us that we don't have our pet anymore. NO ONE EVER ANSWERS THEIR PHONE! Wait on hold 30 minutes...repeatedly...and there is NO answer. CUSTOMER SERVICE IS NON-EXISTENT. They keep charging us for-and sending the product- that we asked them to discontinue.
