Query: heart rate off, no step counting

So just got this in the mail, opened it up, charged it for 2 hours. bind it to the phone through the app. Then nothing, it wont track steps, heart rate works for one reading, but one minute it says 93 bpm, the next 48 bpm. I would send it back but would be a waste of time and money to send it back.
