Don't have dall-e 2 yet. And support is not contacting me

I signed up for the waitlist for Dall-e 2, about a month after it was released. I don’t have the invite yet.
So I contacted support. 12 days ago and still no answer. Also, I think you get an email when you sign up for the waitlist. I never got that either. And my email has not changed since then so if there is anything I can do to fix this.

One last question, if I buy more prompts for Dall-e 2 how long do those prompts last? Like 1 month 2, 3, or 4.

Anyways, thank you SO SO SO SO much! If any of your suggestions work. I am very interested in Dall-e 2! Thank you!
