It was my mistake, and they still helped me
I made an initial mistake when purchasing one of their products, buying a 30-day vs a 60 day. I didn't notice the difference until almost 2 weeks into the purchase, and asked if there was a way to correct the issue -- the cost with a sale going on between the 30 and 60 day was only a little more than $5. As their current purchasing process didn't allow for this, and to save me from having to re-purchase a full 30-day cost at the regular sale price (much greater than $5), they granted me the needed extension. I was relieved for sure, even though totally willing to pay the difference between the 30 and 60 day costs. Customer support also got back to me within a day of every submission I've done, including some mistakes on practice-test answers.
