Refund needed for IMDb pro account

Hi there, I was billed 149.99 for a yearly subscription for imdb pro account and I do not even use this. I need to cancel this subscription and receive a refund please. I didn’t even know anything about it until I saw it on my bank statement. I was not notified in any way at all before this was taken out or asked. Please reply soon as this was money allocated for other needs. Thank you.
