Client reminders

So why is it my clients arent getting the reminders that I have paid this app to do? Very frustrating when my clients get mad at me for your mistake!!! I will not be renewing at the end of my year due to never keeping up with the updates.... This isnt the first issue Ive had with this app!!! I hope this helps for someone that is looking for a salon appointment app!!! Dont waste your money! No one will ever contact you when there is an issue!!!!!
