Raw deal after booking bakkie in for service

Took the bakkie in for service last week , it had no problem with overheating, got it back the same day and paid over R6000 for service of the car. 1 day later the temperature of the car is sky high and cant be driven because of fear of blowing the gasket. Monday the 18th of December i call my insurence to tow the car back to their service centre and ever since its been back and forth emails with their customer service manager, no courtesy car has been offered, no time frame for solution has been given. Nissan as a whole have given us bad service through out and that is why we booked the bakkie in at North west Nissan hoping they would be better, unfortunately its turning out to be a xmas holiday filled with dispair and bad service, such a big company such "****" and arrogant service...Do Yourself a favour, avoid buying any Nissan car...especially an Mp200, seems like Nissan doesnt know how to service them...from Ormonde to roodepoort its the same..
