Sobha Developers — Refund of booking amount in Sobha Sentosa

I had booked a 3BHK apartment in sobha sentosa in September 1st week, and its been 3 months since i am waiting for the refund of the booking amount.
I cancelled the booking within a day, and then i was told that i till take 45 days to get the money back.
While booking i was not told that it will take about 45 days for refund amount, however now its been 90 days and no refund has been processed.
Please look into the matter urgently
