Invisible Fence of TCHV

I am beyond frustrated with Invisible Fence at the moment. Particularly Kim in Galway, NY. We had 3 collars that didn’t work. Two of them were nearly 20 years old so it’s understandable that they needed to be replaced. The other was less than a decade old and a Microlite that supposedly has a lifetime warranty. What they don’t tell you is that the lifetime warranty is void if you don’t use Invisible Fence brand batteries in it the entire time. Of course we didn’t! Invisible Fence batteries = $24 each, others $3-5. We have 4 dogs. First Kim tried to sell me new equipment saying we needed to upgrade. When she heard me on the phone saying we’re going have to switch to another invisible fence brand because she’s trying to sell us new stuff she suddenly changed her tune. So we purchased 3 new collars at $350 each (Kim was nice enough to give us $50 off of each if we traded in the old ones). All we had to do was switch something on the transmitter from 7XX to 8XX. Of course she wanted to do that (more $$$ for her) but we’ve had plenty of experience with the system and could do it ourselves. No problem. Done and the 3 new collars work. HOWEVER, we have one more collar that still worked. It still worked when the system was on 7XX. It doesn’t work on 8XX. I called and she said it was no problem just stop by and they’ll reprogram it. Great. We did that and came home and it still doesn’t work. I called and calmly told her that it still doesn’t work. It’s obvious there has been some miscommunication in her office. Her assistant that did the reprogramming said something about it being switched to 7XX, um no, it was supposed to be switched to 8XX. I was put on hold. Kim gets on the phone and all **** breaks loose and she tells me we need to buy another new collar because this isn’t compatible with that and blah, blah, blah. Needless to say I ended up hanging up on her (much better than me telling her where to go and what to stick where and exactly what I thought of her). I suspect this isn’t the first time she’s been hung up on.
