Three years ago I purchased a computer from Dell with a subscription to Microsoft Word for ~$9 a month. Last year I got a virus and had to reset my computer and lost Microsoft Word.

I recently purchased a permanent subscription to Microsoft Word for ~$100. It was with a code and Word works fine now.

I am still getting a ~$9 fee per month from Microsoft.

My credit card will not stop payment on my monthly subscription.

Where is my mistake? Is it the permanent subscription fake or the monthly subscription?

What should I do? I hope that this is a honest mistake?
