I WANT TO CANCEL THIS STUPID CONTRACT

I NEVER use my Multi Destination Club points. I never go on a decent holiday because my points don't allow me to go in school holidays (and I have 2 kids). When will I ever go on a holiday??!! But I need to pay the management fee which is MORE than a decent holiday in December. I therefore inform you now that I will cancel my debit order and you are welcome to take me to court. This is unbelievable. I don't want this contract and neither want to pass it on to my kids when I passed away. This is the WORST decision I have ever made and I am so sorry that I took out this contract.
