Bad dealership

Good morning.It is been almost 8 months now since I bought my car from Auto Investments and I am still waiting for the spare key of my car.. Really this is no joke anymore.I have been back at the dealership for how many times and send them messages but to only get a reply we are waiting for it.How can't they get any spare keys if Chery is full of stock?I will never do business with them again.
