Wa alaykum us salam. Some what similar happened to me as well. I booked my Altis in the last week of October. On the condition of Full payment in advance, I was given PBO for November delivery then and there. Dealership says they are sure to get the car by the last week of November, but I will keep on bugging them from Mid November afterwards. Meanwhile, IMC helpline first told me that they could only tell me the EXPECTED DELIVERY DATE. when asked, I was replied that my query had been escalated to the concerned department and I would soon be informed about the EXPECTED DELIVERY DATE. Still hoping for the best, else would consider going for the clause of full refund of advance payment without deduction of 2% administration charges, should the car isn't delivered by the end of the tentative delivery month (November).
