Wikipedia Email Support
Wikipedia provides their best customer service over email. If you were hoping to talk to a Wikipedia agent live right now, on the phone or via live chat, this might be disappointing. But at least you know there should be a person on the other end helping you, and it may take less time overall to send a few emails back and forth.

Wikipedia Phone Number
Wikipedia doesn't have a phone number, which is a shame.
Wikipedia Live Chat
Unfortunately, Wikipedia does not offer live chat as a channel for customer service at this time.
