Customer Support

One of Jack21’s downsides is that their live chat is done through an e-mail messaging system. You are only given an e-mail address and a “Message Us” section in their website to clear-up clarifications and confusions. This can cause problems to arise, as they will not be addressed instantly. Customers can contact them through mail. No other contact details such as hotlines are given through clients, and this can delay communication processes.
