Great tool Easy to use and has functionality I need. Think there is some maximum number of pages you can convert at one time so have to break it up.

Slight misunderstanding promptly resolved There was initially a slight misunderstanding, however, I was lucky enough to get Dee again when I reopened the chat. She had thought that I just wanted my subscriptions automatic payments cancelled. Really I wanted the payment stopped and the subscription cancelled. Thankfully she worked up until the last minutes of her shift to help me. She was excellent help!
