Kia Tygervalley service department terrible service

Due to the dealer/service department's negligence, my service plan expired. I took my car in for a service in June, was advised to come collect it and bring it back in September. When I took it in last week, they phoned me and told me the service plan had expired. When I phoned Liquid Capital, they advised that my vehicle should, in fact, have been serviced back in June. Also, I was assured of a loan vehicle when I made my service booking, when I got there last week the sales guys had NO idea who I was, so the service department didn't communicate that with them. Thankfully they made a plan for me. The Kia Tygervalley service department is horrible. The service adviser I dealt with, Liezel, had a really bad attitude and kept trying to pass off blame to anyone and everyone else. She also promised someone would phone me about this issue last week. I am still waiting.
