Error: Cannot Purchase SMS Credits

I recently joined YCBM specifically so I could send SMS reminders. After setting everything up and purchasing a subscription I am unable to purchase SMS credits. Each time it gives me a red error box saying that SMS credits are unavailable for purchase and to contact support. Support has not responded in over two days. I’ve also tried multiple cards. I need to run an experiment soon and this feature is important to sending out reminders. Anyone having this issue?

In the console there the response is a 403 for the PUT request.
I’m using Chrome and have also tried in Brave.

@beck I am pretty sure we got you squared away through support. We block the SMS purchase to avoid bad actors from abusing things.
