Nah,why on earth would someone hurry to close a car's door while talking on phone? He was going to kidnap the girl for sure! But the kind woman saved her. I think he was probably talking to another kidnapper or his boss or something...
Having a closed door makes it harder to kidnap. In the video he had his phone to his ear like he was on a call, but as soon as the girl walked from the shop he went to snatch.
