I'd be frustrated too! I am currently paying for 3 more bps from two different breeders. Both give me practically weekly updates (without asking) and have been more than willing to send me pictures whenever requested. IMO customer service is HUGE, and if you're "too busy" to help me then I can take my business elsewhere. There are more than enough awesome breeders who are caring and more than helpful who would greatly appreciate selling me their animal. I get a response via email within hours of mine, and even text in one case, even a call out of the blue for an update. My 2 cents. Good luck!
Edit: for the record I wanted to add the breeders I am dealing with are Coiled Constrictors and Eclipse Exotics.
