Bad Service at Nissan Eastern Cape

Booked my Nissan Qashqai at NEC on the 29th Dec. On the 30th I called NEC they advised that they havent checked the car yet to see what the problem is. They called me later to say it is the clutch that has given in & it wont be covered under warranty I must pay for it. A quotation of R4k was sent to me on the 31st & I gave them a go ahead. Later that day checked the quote again to realise it is not my quotation sent them an email no response. Received a response on Mon 4th Jan & a quotation of R15k. Gwen (Costing Clerk) called me to say the car will be ready on the 6th at 15pm & I told her I will come on the 7th early morning to leave for CPT. Got there at 10:00am Heinrich ( Service Advisor) told me the car was not ready there is a master cylinder that needs to be ordered, the Service Manager George asked me to give them an hour & it will be ready as they will use a part from a new car, got ther after an 1hr & half another part was giving them problems , waited there with my family whole day after a long fight we left at 4:30pm without my car. Was given a Micra with no Petrol to drive 300km back home. Only got my car on the 8th @11:00am & I had to call them their service was bad.
