Error Provisioning User - User status - suspended

Question

I created a new Sendgrid addon in Heroku:

heroku addons:create sendgrid:starter

After that, I entered my Sendgrid account and it said that my account was suspended (I just created, how is it suspended?)

So, I had a brilliant idea (NOT!): I've removed the addon and tried to create it again. Now I get the following error from Heroku:

 An error was encountered when contacting the add-on partner to create sendgrid:starter: Error Provisioning User - User status - suspended

What should I do?

Answer 1

So, after some research, there is nothing that I could do. I contacted Sendgrid support (https://support.sendgrid.com) and they solved the problem (although they never told me what was wrong in the first place).
