Annoyed and disappointed in Toyota support

My vehicle (Toyota Fortuner) was taken to a dealer for repairs on the 17 th of October 2018. It took the workshop 4 days to find the fault and they then advised me that the ecu was faulty and they ordered the part but it will take 15 days to get. The part was ordered on the 22 nd of October and supp**** on the 15 th of November. The car is still in the workshop and they still can’t give me a delivery date. I’ve been a proud Toyota supporter since 1994 and owned several models and I just feel that this is no way to treat a client. I also asked the dealer for a cirtousy car on which they said they can’t help me. I also contacted Toyota SA client care hoping that they’ll assist me to resolve this but I’ve had no support from them. So I’ve been without my vehicle for a month and still not sure for how much longer it will take them to repair it. In the meantime it’s cost me thousands for car hire . Hoping that I’ll get some support from here and if anyone reading this is in the market to buy a vehicle that this will help them to choose a brand
