@Tiffany456 I have a very small experience with Airbnb as a guest only. I also had recently an issue (it was not bedbugs, it was the advertised A/C was missing and I stayed in spite of that). I also emailed the Airbnb support within 24 hours of check-in and I messaged them again and again (despite some people here who said that I was wasting my time and why ask for a refund when I stayed...).
Anyway, in my case it took 14 days to the Airbnb support to call me and to offer a resolution.
So I would say, keep messaging and calling the Airbnb support, they may eventually give you an answer.
