Some people are just impatient. But in this case, you have no proof that she actually got it, so you don't have a leg to stand on. If she is making a lot of trouble, as far as I am concerned, you can either refund her and forget about it (you don't have to talk to her--just credit back her card) or you can just ignore her and hope she doesn't do a chargeback. As for the bad reviews all over the web, I have learned that even though companies have massive negative reviews all over the web such that any one of us would be lying awake nights wondering when we are going to be going out of business, companies stay in business. The reason is that most people don't read those reviews. Or they don't care. This is how real skeevs and ripoffs stay in business year after year. I see it over and over in my niche. It made me quit clenching so much about the bad-review issue.
