1-800-828-0228 or 1-877-939-3732 (this only works in the US)
If it's really busy and you can't get thru, try 1-888-870-9173. It's for their Spanish desk. The CMs are bilingual and they will help you even if you don't speak Spanish. As soon as you hear them pick up wait 2 seconds and press 1 and then wait 15-20 seconds and press your zip code followed by your phone number. Then it will ask you 2 questions, just press 1, wait about 8 seconds and press 1 again.
These steps are from a previous post but I tried it once and I did get connected and the CM was happy to help me in English.
