Dissatisfaction with platinum leisure

I would like to express my level of dissatisfaction with platinum leisure, I sent an email to them on the 27 October 2017 for a booking on the 30/11/2017 – 3/12/2017, I was advised by platinum leisure that I can only book from the 30/11/2017- 4/12/2017 of which I did. Now I receive an email advising that the dates they've given don’t have the complimentary option that I want and therefore I should choose new dates giving them a month. . I’m appalled at the treatment given to us ( as clients) when you sell their product to us they don’t tell us that making a booking will be so difficult and STILL not have the service rendered! Now that they've debited my account you’re not keeping to your end of the deal...that is plain *******!
