The site does not have it visible on how to use the credits or the cost of doing certain things. I purchased 20 credits and sent 1 chat and they charged me 7 credits when it is 1 credit per chat. They said the person was offline so that is why I was charged but he was not and that is not stated on the app or site. I spent $60 almost In 2 days because I was unaware of how to use the credits and the cost. I only found out what I just shared due to live chat with an agent who was a jerk.
