I went to one of these sales presentation things after being approached by someone from The First Group at Dubai airport a few months ago, he promised a free tour of Dubai, lunch and there was even talk of an Emirates Airways Gold card. The tour was to building sites only, lunch was a coffee and the gold card never happened. The presentation went on and on for hours despite me telling them numerous times that I was not interested, to wrap it up they asked if I could provide them with a good review, I refused but was told I wouldn't have to write it, they would do that and post it in my name.
Now I have a lot of time on my hands due to the lockdown, I decided to have a bit of a look around various review websites to see what was on line about them, I found their rating is a lot higher than what they have earned and that they have a long history of writing their own fake 5-star reviews on this and other review websites. They actually have 2 of their own fake review websites. If you google Dubai Property Reviews and Dubai Investment Reviews they will be easy to find and they are blatantly fake. So, they are lying and cheating their potential clients before they are even clients. This would be a clear indicator of what will happen if you invest with them.
