I created a landing page, set up a callback button, and then got sick. The button was supposed to function during a 7-day trial period. I reached out to support asking to extend this period. And what do you think they replied? They said: YES! Whenever you, Tatiana, need it, we will extend it! Now that's real SUPPORT in every sense of the word! I tested the button, and it works great! I recommend it!
