Hi everyone!

I have just bought an apartment in Dubai Marina Crown and although I have already paid the full amount, I still haven't got the keys. Vakson, who sold me the unit, first told me that I had
to pay maintenance fees upfront at a rate of 8 dhms per square meter. They also asked me to pay 2000 dhms for DEWA connection. This was confirmed to me by e-mail.
I sent them the amount last week and they sent me another e-mail asking for more money as Maintenance charges
are now 12 dhms per sq foot! On top of that they want me to pay for unit registration with the lands department which I know is optional. I know I am being taken for a ride but is there anything I can do as I don't live in Dubai (which my family and I like very much). Isn't there some sort of regulatory body in charge in Dubai to deal with these matters.
What's the contractual amount I am required to pay to get possession of my apartment? As I want to lease the apartment this is causing further delay and to be honest I am
very surprised by the way business is being done in the UAE.
Surely the authorities should look into these matters as these
unfair practices (to avoid using another name!) give Dubai a bad name. But apparently I am not the only one in this situation from what I read on this forum.
Any help welcome!
