How To Find Correct Battery Online/Hacker Locked My ComputerNitro 7 - AN715-51

Initially my acer was not holding a charge very long after unplugging. Then computer screen was black while plugged in and power light on. Desperate for info I needed I contacted the geeksquad for remote help.I then unplugged and removed battery,went thru steps that was outlined and was able to get back online. Three days later received an invoice stating I had been billed 349.00 for virus protection from geek squad. All went down hill from there, The claim they had re imbursed me wrong amount and I would have to refund. Long story short when I called them on what I was sure a scam and refused to pay ,I was threatened that I would be sorry if I didnt. Next thing I knew my computer was locked with a demand for 500.00 to unlock it.

So my questions are how can I be sure am ordering correct battery HP15-bn070wn online and is there a way to unlock my computer without taking it in.

Thank you,Bonnie
