Festiva wants my timeshare back and sent release papers for me to sign. it is a deeded timeshare. should i give it back?

i have been contacted by a company in Portland Maine called viablesolutionsonline.com, although the information given so far checks out i am unsure as to the legitimacy of the company as i cannot find any reviews for them and they are asking for a wire transfer from me to enable them to proceed with the transfer of my vacation package(not a timeshare). for their part Lloyds bank have voiced their distrust.

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 have an offer on my Vida Vacations timeshare that is nearly twice the investment cost. The offer is from a middeman organisation called Tradingconnection.online, Sarasota, Florida, USA. They have a working phone number and a web site. Sent me a poorly drafted semi-legalise sale agreement that looks shady. Ever hear of them? Thanks , Lloyd Sanford,
