Sobha Developers — cheated by salesman/sobha

When we booked flat in sobha silicon oasis, assistant manager mr. Abhilash gave us an offer of two gift vouchers of fifty thousand each. He didn't give us that in written and when we asked also he was reluctant to give it in written and informed us that he had taken care of everything and we would receive the vouchers shortly. But after that he never answered our calls and now the senior general manager sanjith p says that he cant do anything as there is no proof of such an offer given.

We strongly believe that this is a clear case of cheating by sobha. Otherwise why didn't the salesman who is well aware of sobha's policies didn't give us that in writting? Is this the sales strategy followed by sobha? Is sobha that much desperate to sell the units by giving false promises to customers?
