My Wife and I bought my son a block of 10 lessons with A Class from Chatham in Kent. My son managed to get 4 lessons with an instructor and then the instructor didn't turn up and informed my son after the lesson time that he had personal problems and would have to rearrange. 3 weeks passed with no contact so we contacted A Class who gave us the name and number of another instructor. This guy waited ten days to get in touch and then today (20/09/2016) sends my son a message to say that he generally finishes by 17.30 (my son works until 17.00) but will occasionally do 19.30 or 20.30 lessons but has no availability until 04/10/2016 or 18/10/2016!! We have now contacted A Class to demand a full refund as we do not feel that our Son is receiving the service which we have paid for, the guy says he will refund but we will see when we visit their offices tomorrow, I do not feel confident to say the least. If they refuse to refund, who can I lodge a complaint with?
