Bluehost Inc. Forced auto renewal, unable to cancel account, harrassment Orem Internet

My company (sole proprietor owned),  took a 2 year Bluehost domain account in September 2013. Because the company shut shop in 2014, so one week before auto renewal of the account on September 16, 2015, I asked Bluehost by phone, online chat and via email, not to renew my account. Bluehost asked me to fill a form, which they never emailed to me. I called multiple times (as per cellphone bills), to no avail. My credit card was billed $311.52 in late September 2015, by Bluehost.

I disputed the charge with my credit card company, upon which Bluehost deactivated the account. Due to the limited time, I was not able to win the credit card dispute. Bluehost finally sent me a form for cancellation of the account on November 22, 2015. But they have still not refunded the amount paid - $311.52. I have spent more than 60 hours trying to fight the case with them - all because I did not want to renew my account, but have been unfairly (and illegally?) billed. Not only have I lost 60 billable hours which I had to take from my working hours, but have also felt mentally harassed by the Bluehost team.
