KIA HAS THE WORST AFTER SERVICE AND ARE RIP-OFFS

In 2017 my mom bought a Picanto from Kia, the deal she got and stated in her contract say that she will get an unlimited service plan for 5 years. Her car must be serviced for the 60 000km now they are telling her she needs to pay for it. The branch she bought the car from agrees that she should not be paying but all their branches are not linked systematically. They told her to link the system takes a day or 2 and then she can take the car for service. It has been 2 weeks,she is almost 2000km over 60 000km and everyday its a different excuse. The funniest excuse they came up was that her car's deal was used on another car similar to hers. I feel they a bunch of ****** and their after service sucks and is extremely unprofessional.
