CX failing to honour the exercise of the option is a contractual breach, the liquidated damages being the reimbursement of OP's QF fare.
This (bolding) is the crux of the matter. It is on CX to accommodate the OP's request from the options provided by the CoC.
My interpretation of the original post is that the OP requested the options but never informed CX which they would like to take. By doing that they simply became a no show.
