Have an issue with your channel and want to contact YouTube directly about it? Then just call (650) 244.....Ha! Like it's going to be that easy. As the second largest search engine in the world (the first for video by a country mile) with a billion active users a month and over 1 million partners you are not going to be able to just pick up the phone and speak to someone, however urgent or frustrating your issue may be. However, YouTube do provide resources online where you can submit a request for help and we'll take you through these options.
Contacting YouTube About General Enquiries
YouTube do have a contacts page where they will point you in the general direction of how to contact them depending on what you need. They give an actual bricks and mortar address too:
901 Cherry Ave.
San Bruno, CA 94066
Phone: +1 650-253-0000 | Fax: +1 650-253-0001
They also give you a phone number to ring (and, adorably, a fax number). In reality, the phone takes you through to an automated Google switchboard which will put you through to a living, breathing human if you know their extension number. If you don't, you can choose options to contact them regarding advertising, recruitment, Google products, info on the Google Search Appliance and, also, customer service. Don't get too excited though, the customer service option will suggest you visit the Google website for further info.
Contacting YouTube About Channel Issues
There is no way to directly contact YouTube either by phone or email for any general support issues. However, you can contact YouTube staff by completing and then submitting the correct form provided by them or by using some of the tools available online. YouTube encourages the use of this approach (even though you don't really get a choice in the matter) as it makes things more efficient for both parties. Often, the user will find that they can resolve the issue themselves without taking it any further. Forms that are submitted are subject to a decent response time of around 48 hours.
Regarding specific help for technical or other issues, YouTube provide the following avenues for contact:
Account Recovery - If you need help with recovering your account. User name or password is required.

Other Ways To Contact YouTube
YouTube are very active on social media, as you would expect, and it's a long shot but you could try getting their attention via their Facebook or Twitter pages. Bear in mind that they have more followers on Twitter than the population of Malaysia and their Facebook following is over 75 Million but you never know.....
They also have a forum over at Google Products which can be very helpful. If your question is relevant and on topic you'll often find the answer here (although it may not be what you want to hear, particularly if you've broken the YouTube T&Cs).
Hope that all helps.
