Expat Properties — investment in land in project carnival in 2015

I investment in the project carnival in 2015. I have paid in full of a half acre land.
I received a email in mar 2019 saying registration has started. When i contacted the concerned mr. Nitesh decosta (Dubai office) i was told the survey plan had changed and i will have to choose a new plot from the new survey.
My earlier booking was for 21780 sq ft (0.5 acre) inclusive of roads. Towards this, i was offered a new plot with an additional area of 1801 sq ft in carnival survey no. 127/4 at a additional price which i paid on 27 jun 2019. I was told the poa papers would be posted to me in england within 1 week as i am out of country.in july i come to know that mr. Nitesh has left the company and since then there is no one to answer my queries.
