Facebook ads still broken. Worst conversion ever!

Yesterday I tried to run my campaigns again after I decided 2 weeks ago to stop them all as it was like burn money. I just review my campaigns today and the conversion is even worst than when I decided to stop them. Facebook just burn all the budget with no conversions, something that it never happen to me before till today. The conversion was horrible, worst than ever but at least I had some sales even loosing money, now not even that.
I think that probably facebook is using bots to generate junk traffic to the site.
