Very, very poor customer service.

My car due for service with 15000 km, I came for service at Kia motors and they are telling me that they can not service my car because it is late sfor service, am asking them how because it suppose to come when it is 15000km, they are telling me that am suppose to come in 12 months, no one told me about that, it is my first time to buy a new car, so liquid capital is been paid every month, today am bringing my car they say they say am late, no one explain to me as a first time buyer, I was not even awere of who is responsible to pay for my service I was just told that am not paying for my service I must just bring the car, I was speaking to Leasego at liquid capital and she is also saying she can't help, I ask refund for the money paid the whole year, she keeps saying policy of which no one from liquid capital called me to explain from day one. and I ask to speak to a manager, she keep me on hold then she drop the call on my ears. That is the service that they are giving to a first time customer.
