TheChaiBox review for Mailchimp Email SMS Marketing

In my 2 decades of working in/around Technology platforms and companies, I have never come across one with such lack of customer support as this one. No one ever responses real time (or close) to chat. Email, you are lucky if you get a response and if you do, you are paying pro to get links sent to you for the free articles. One thing we needed with synching our emails was to move our tags to group of our emails. Tags will not come over and there is ZERO SUPPORT EVEN IF YOU PAY. Nightmare - just stay away. Might even need to reconsider MailChimp for recommending this as a tool to use!
