Not sure where to ask this ..I'll try here.

My facebook acct. has been disbled. i was trying to poat an ad in marketplace & because my acct. was inactive 9i dont use it much0 they asked for my mobile phone no. to send me a text to reactivateacct. . Problem is.. I've never owned a mobile phone! (am i the only one in the world?) I tried putting in my home phone but no luck. I cant see any way of contacting FB about this...no email addresses or phone numbers? and i'm stumped. any suggestions? thanks.
