Unable to assist in fixing my Kia Sedona

I have phoned Kia Northcliff three times to ask them to assist me in starting my Kia Sedona. I was given a number to phone Kia Road Assist, MYSELF. They came out and can’t seem to start the car. Kia Northcliff service department keeps telling me they can’t assist until next week. Is this how they treat a loyal customer!! What am I meant to do, I need to see clients and go to work. NO ASSISTANCE AND BAD ATTITUDE FROM EVERY SINGLE PERSON IN THE SERVICES DEPARTMENT.
