Unbelievably bad customer service. I needed heartworm and flea/tick meds for 6 dogs, so tried Allivet because the cost was a little lower than other sites I've used in the past. What a huge mistake. First, they said they couldn't contact my vet. I called him, and he called them. Turns out they were trying to contact a different vet (?) about my pets. Over a week later, the website still showed "Rx unconfirmed, so I emailed them. No response. Next, I called them. They lied to me twice, saying that my vet had just called them the previous day (lie #1) and that he had only confirmed the prescription for 1 of the 6 dogs (lie #2). I cancelled the order. They must be used to that, because the woman I spoke to was supremely disinterested in the entire conversation. Since they're apparently not interested in selling the products they advertise, I'll be carefully checking my credit card statements for unauthorized charges.
