Facebook said that I added someone and I didn't?

So apparently I sent a friend request to this one girl that I don't even know. And she accepted. The problem is, I DIDN'T SEND THAT REQUEST. Now she texted me, why did you ad me as a friend and then delete me? You can be friendly. I don't know how she got my phone number and I don't know what to reply, please help.

E MAIL ME HER NUMBER I WILL SORT IT OUT FOR YOU

That happened to me. NO WAY did I friend the girl, but it said she accepted my request.

Some guy is probably hacking everyone's account to get as much friends as possible. lol
