I made a mistake and bought a year subscription instead of one month as I needed, I immediately emailed customer support and thought I would be waiting days for a reply if I was lucky, but to my surprise I received a response within 2 minutes. She offered to change my subscription and refund the rest of my money, I of course excepted and they changed it immediately! ***** ******** for your amazing customer service! And your forms, that have been time saving!
