Walmart review: auto oil change, filter change and tires rotation

They didn't do the service correctly
So I went to Walmart auto center at Everett, Washington to change my car oil and filter and to rotate my tires it was 2pm so they asked me to wait so after 3hours waiting I asked them what is the problem because I see my car from the window is locked and nobody doing anything with it so they told me just tires rotation so in 2 minutes they asked me to pay for the services they did so I asked them a sample question how you rotated my car tires in 2 minutes really (charging fees for things that not done scam) anyway I paid the fee and then I took my car and driving back home and it shows me on screen Maintenance required how is that so I went back to Walmart auto service and they wanna me to wait in the line outside the auto center wow waiting again to explain my issue then the worker told me take your car to Toyota to resolve this issue so I told him ok after the long waiting you are telling me to go to Toyota and then I told him ok make me a refund and I go to Toyota so he didn't answer to me with yes or no so I went inside the Walmart and the girl was so rude to to me she told me we not going to refund anything so then I realized that she charged me for chassis lubricant that is not for Toyota Prius C (my car) and that they didn't performed this service so I told her and she agreed after she asked the guy that changed my oil (if it's really he changed my car oil)then she refund me the chassis lubricant fee but not the oil and rotation fees so in all that nobody told me sorry wow instead everyone in Walmart (Walmart worker)was blaming me anyway I after 30 minutes so total waiting maybe 4hours they resolved the issue so I took my car and back home wooooow I'm driving my car and my speed 80 so I got confused so after I checked everything while I'm driving I realized that they changed my oddometer from ML to Kilometer this way my speed 80 kL not ml can you imagine so how I can trust that they changed the oil and they did the filter change and rotated i got the most bad experience in my life and I'm still waiting for a refund . I'm waiting for refund because honestly I will go to Toyota to perform this services again .
