https://twitter.com/ZyngaSupport
Directions - go to link above, create a twitter account (super easy, took me 2 minutes, including confirming the email) then just on left column on the support page in the link, where it says "tweet to zynga support" type "I didn't get my bonus 12x stove from summer song" right after the @zyngasupport in that little box, or whatever your issue is....
After a while you will get an email to whatever account you used to sign up saying zynga support is following you.
Then zyngasupport will tweet back asking for your FB user id in a DM (direct message).
So go to your twitter home, (just go to twitter.com and that is your twitter home page) and click the little gear icon at the top right, click direct message, and it opens like a text messaging screen.
In the top box type @zyngasupport and in bottom box, paste your FB user ID and specifically what you want. For example "My cafe refuses to load, I keep getting the retrying! I already did the three things at the top of the game under the help button. Please Help!"
then hit the send message button.
P.S. the 2nd time I used twitter I had to do it twice before they "followed" me. Give it about 2 hours before you tweet again.. also make sure you are within their working hours...
