Unscrupulous service provider

I joined Touch down holiday club in 2013 and opted for platinum package that entails 5x Mid week or weekend holiday breaks, and currently three or the 5 have been used up. At the present moment, my challenge is that they are now refusing to hourner the remaining 2x holiday breaks both Goodness and Natasha who are part of management are ignoring my calls yet all my premiums for 60 months have been paid in full. They are refusing to book for me telling me my membership has been canceled, whereas fully paid up.
