Cannot upgrade my plan, cannot contact support

Here’s my story:

1. I sign up on box.com
2. I fill in all information.
3. I go to upgrade page, choose my plan.
4. Your form does not accept any of my BUSINESS debit or credit cards, my VAT number, and other details.
5. I try to contact support, only option is this forum (https://community.box.com/).
6. I try to start a question, you suggest me to contact you via https://www.box.com/pricing page
7. I contact you there, you tell me that I need to contact you on the https://support.box.com/
8. I go there, it forwards me to the community forum (https://community.box.com/)
9. I ask chat agent to contact me with human, and it ask me to ask itself again.
10. Now I am stuck in the loop.

I am sorry, but if you call this a good system, you are extremely illusional.

I do not understand how you make money, if I am as a regular customer - fail to give you money.

Will I use box.com after this? Nope.
