Part not available to fix Tata Indica

The Tata Indica's Fan in front by the radiator stopped working on my way to work on Friday, 6 November 2015. I phoned Tata Centurion (Close to where I work), but they could only assist me on Thursday, 12 November 2015 knowing that the car tends to overheat without a working fan. I have no other means of transport therefor I have to have my car. I took the car in on Thursday, 12 November 2015, 07:00 and I gave them a list of all the little things that was not right when I phoned to book a place. List: Fan, Head Light, 1, 2, 3 ,4 Fan switch, Breaks started to shudder after Tata Centurion replaced the break pads and I have ordered a Air con Vent which i have been waiting for which Tata broke but never recorded on the system which I now also have to pay for. They only phoned me with the quote at 11:47 without looking at the first thing on the list the fan. I enquired and then only did they start investigating. Tata sleepover night 1. On Friday they told me they did not have a part to complete it my car needs to stay there 22 days for them to import the part from India. I complained with Christel and she said they would have the part on Monday. It is Monday - no part no solution yet.
