I engaged with a Doha Legal firm. Not cheap but I got my investment & apartment back after they "auto-terminated" without following the contract.
The words used by the lawyer and I were identical but since this was sent with Lawyers firm heading, it seemed to prompt a local response from Damac for which we reached agreement.
To date, Damac legal in Dubai has not responded. The courts could be expensive and the process lenghty.
Damac have been in trouble in Dubai through RERA(Real Estate Regulatory Authority), perhaps it's time we had a QRERA.

My advice, stay away from DAMAC, if possible.
