WRONG INFORMATION AND RUDENESS

I recently extended(3month and half ago) my service plan with liquid capital 105000 service and consultant informed I can continue servicing my car when service is due and on Monday(02/10/2017) took my car in for service and the dealership called liquid capital and they told the dealership that my service plan was in a waiting period and I called liquid capital as this was new to me they told me they will extend my kms so it goes till the last days of waiting period and I called Friday(2017/10/06) spoke to Andile and she told me they wont extend my kms and is my problem I should service the car with my money,i told her you guys gave me wrong info from the beginning and I asked to speak to complains department and she put the phone on music mode and it kept ringing and ringing I waited and when she eventually decided to answer she heard it was me she ended the call.i regret taking a service plan with Liquid capital cause now my car is due for service and they expect me to park my car and walk until they day they decide to cover my service
