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

I’ve had a call from a company called Timeshare helpline services saying Timeshare is going out of business and they want me to have a zoom call with regard to getting all my money back. Is this a scam .

My husband and I bought one week of timeshare 1999 and another week at the same resort a few years later at Bahia Blanca Gran Caneria. We continued with maintenance payments till his death in 2004 I continued for a while then misguidedly tried ‘Sell my timeshare’ in 2006. They are under investigation by police and I got my £6000 back via sect 75 with Nat West about 2017. I used Preteorian Legal to get out of the annual maintenance contract as they broke off their contract with Bahia Blanca via a Tenerife address who owned the site.
However the initial outlay of £12,000 I am still out of pocket. As I am now 67 years old this money would now be useful to me. I was informed last year the company we bought our first year with at Bahia Blanca sold the business on 2000 and we had no new contract with the new owners for maintenance but we paid it never the less

Our solicitors say they will provide a notarised letter stating that our timeshare contract with MGM has been terminated and that under no circumstances should I contact MGM – if they contact me for unpaid maintenance payments I should contact the solicitors. I am feeling more and more uneasy about this as I was hoping for a notarised letter from Muthu saying that the contract had been terminated, Will our solicitor’s letter stand up in court ?

We have been contacted by
NewGate Legal SL who have offered to sell our timeshare.

Should we go with them or would you recommend another avenue to go down.

Diamond resorts want to charge for being unable to use whilst in lockdown

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.
