Is there a more polite, more correct way of making a formal complaint about a business that appears to have defrauded you?
We paid an animal behaviorist the required fee for a consultation. The fee was meant to include:
1. 90 minute in-home consultation in which the behaviorist would observe the pets, ask questions about their history, etc - gathering information
2. Written plan about how to deal with the problem going forward
3. Recording of the consultation for us to refer to
4. 3 months of follow up advice via email and phone
The consultation went smoothly - the behaviorist was late, but she did text to let us know, so that was okay. She was great in person, very friendly and it sounded like she knew what she was talking about. She left, and we have not heard from her since. It's been a month. We have texted, left phone messages, and emailed multiple times, but she has not responded in any way.
Is there a proper way of handling this if we get to the point where we feel we need to make a formal complaint with the state? Technically, I believe this is fraud. She took our money and did not provide the services we paid for. (Or at least not ALL of the services.) Should we let her know that we're considering making a complaint before we do so? Is there etiquette about this kind of thing?
