Is there a market for selling my RCI Points with Pearly Grey Ocean Club?

Unfortunately, there is no option to rate minus otherwise I would have given -10.
Bought a trial membership and paid over £4000. We only managed to take the complimentary week. I had made enquiries about the interval as I was planning to travel but did not due to COVID.
I was reassured that the trial membership has been extended. Last year I called to make enquiries about
2 weeks in Mauritius and I was told that the resort in Mauritius was not operating at the time of the phone call. I was being given a few other options but they were all either on the red or amber list.
In the last 2 weeks after numerous failed attempts to contact CLC / Interval or being pushed from pillar to post or being given wrong numbers plus and no reply from an email sent to them, I eventually got hold of someone who told me that although my membership had been extended my interval weeks was not transferred?? and apparently, Intervals are a “completely separate body”.

When I had made the enquiries last year at no point I was told that the interval had expired.

My argument was that there was only 1 direct debit for Trial membership which included service from the intervals. it seems that there was no consideration about the fact that the contract was drawn up pre- covid.

This is blatant theft/ fraud.

I am the executor of an estate following a death.

My client had a French timeshare with Clubhotel and I understand that there is a French law where whoever inherits it can cancel the timeshare within 2 years of that inheritance.

My client died on 27 February 2021 and the estate is now ready for closing.

My client had very little in possessions and the small amount of money he had in the bank did not require probate to be granted to access it.

My client was receiving maximum UK benefits during his last 10 years of life including guaranteed pension credit.

There was no specific person to inherit the timeshare in his will and the person who would naturally inherit it would be his 77-year-old son who has Parkinson’s disease and other complications. Dealing with this timeshare problem in the next 18 months could create enough stress to shorten his life.

I would be grateful for some guidance as to how to deal with this problem.
