The best way to get in contact with the QuickBooks Online Support Team is to go through the callback request steps. This will ensure one of our agents get in touch with you as quick as possible. The blue box where you enter your contact information gives an estimated time when someone will call you back.
Although, where it's been two hours since your last request, I recommend filling in your information again and waiting for an agent to get in contact with you. However, you can post your question here in the Community, and we can help you with any issues you may have.
Please let me know if you get in contact with support soon. I'll keep an eye out for your response.
