Yeah, nothing like murdering the closest thing she'd had to a father, crippling her friend and trying to psychically force your way into her mind to make a girl fall in love with you. And that was all just in the one day, that she was there for.
if it helps: They still had a bond-scene at the end of the movie. (it's not just a camera trick: The sound effects where there too) So even IF Snoke didn't lie it is still there. That said, all the material of TFA already states that they sense "a strange connection". It's more likely that Snoke lied.
