I received a call about 6 weeks ago saying they'd sent me the wrong paperwork. I immediately phoned and the person who answered for this business answered the phone saying Rockhill vet clinic. I stated that I was calling companion and she said "sorry, I used to work there." She then confirmed that yes they'd sent me the wrong paperwork. I explained that I'd never gotten any. She did not verify my address, but just said it was on the way. I called again 7 days later, was told again that it was on the way. No verification of address. Three weeks later I called a third time. They're now answering their phone with the correct business name, which is progress. Still no correct or incorrect paperwork. She verified my address this time and I was informed I'd provided it incorrectly. I cancelled requesting an email confirmation and a written confirmation. I've not received the first, and I'm assuming I won't receive the second. If this is not a scam, there are some flaws in your procedures.
