Flexi Holiday Club - Club Leisure

I booked a 8-sleeper unit in PE at Brookes Hill with Clubleisure/Flexi Holiday Club with whom we've been members for many, many years. The booking was done at the end of Nov.2020 for occupation 1 Jan.2021 - 8 Jan.2021. I had to pay almost R13 000 in exchange fees and they used ± 32 000 of my points. My wife, 64 years old, my daughter who's visiting from the USA with her 2 kids aged 11 & 13 and my other daughter with 2 kids aged 4 and 1 years were going to enjoy a much needed holiday at the sea. However, with the "new" amended Lockdown Level 3 this is not going to happen anymore. Needless to say the disappointment to all, specifically the 4 year old! I contacted the Club to cancel and asked for a refund of the exchange fees and my points with they claim is not valid due to their company policy that you have to cancel 21 days in advantage. How do they expect me to cancel 21 days in advance if the president announced the new rules on Monday evening!

Totally useless response from them!!
