Bad service and respond time

My car broke down on the 27th of december 2015. Eince then my car is standing by TATA to be repaired. They spoke to me and say my car is going to standfor 2 MONTHS cause they need to order the parts from INDIA. i phoned them to arrange a courtesy car cause u can sit without a vehicle for 2 months. They told me they cant arrange for one cause they have none. So how must i get through without a car for 2 months.
