have you any experience of Fullbrook Associates or Proactive Solicitors with regard to timeshare termination

Whilst staying at a Heritage Resort in Spain, we were approached by their manager to see if we wanted to dispose of our timeshare and offered a way to do so. It involved paying a lump sum and in return, they took our timeshare (2 wks in Tenerife) so we had no further responsibility and gave us a 3 year introductory membership into the Heritage Resort Club with the promise of a holiday each year at a one of their resorts and at the end of the 3 years we can walk away knowing that we have no further responsibility to our timeshare and no requirement to join their club. I am concerned this may be a scam. Do you have any thoughts on this?

I bought a week way back in the early ’90s at Puerta Calma resort in Puerto Rico in Gran Canaria. I paid over £8k and it came with 2 years free fees.
Roughly 6 months after the purchase I realised it would be of no use to me. I contacted the resort repeatedly informing them I did not need the week I purchased and could refund my money or as the management of the resort could they resell it for me. I never got a response to my numerous requests.
Then I started to get invoices for the annual fees. Again I contacted them again I was ignored. In voices kept coming for several years then stopped and I’ve heard nothing since! I honestly believe I was robbed of the £8k?
