I have paid, so far, to ARY AED 17.000 more than it was promised for a one bed apartment in Italian.

Having said that, I want to have info about another matter:

I paid to ARY AED 6,300 for “Nakheel Registration “fee” back in year 2005.
And now they charged me same amount in the name of “Land Registration Fee”.

I sent their demanded money (the subject money and much more under "Other Expenses"), immediately, as I did not want to provide them an excuse for cheating me and canceling my apartment or charging me a fine for a delay in dues payment.

My question is: Am I supposed to pay those BOTH payments separately or it is only ONE payment and ARY is simply exercising their known ethics, they are now very famous for?
If I am right than I can at least take the matter to Nakheel, if I am ever successful in getting the keys from the cheaters at ARY.
