Flexi not delivering what they promised, selling lies

I signed up with flexi in November 2016 and was given 3 vouchers for 3 years (free holiday anywhere locally for 7 days). In January this year I tried to book for a holiday in September but was told “No you need to book 6 weeks before the actual holiday”, ‘I guess the agent forgot that piece of information’. August I tried to book again and was told “Sorry its peak season”. Ohk understood. Now today tried again, to my surprise the consultant tells “you can only bring 4 people 2 adults and 2 kids” BUT the agent specifically said I can bring upto 6 people (4 adults and 2 kids). Now flexi how I we explain this to the other people? Did your agent specifically told me **** just so I can signup? Or nje you as club that is exactly what you are selling? #soDisappointed
