Complaint Review: kwik kar lube

I experienced problems with my car, including a check engine light 1 month ago. Upon my arrival at kwik Kar Lube, they did a diagnostic to determine the problem, which was a gasket valve replacement of $330.00. I was told that I had an oil leak on my spark plugs replacing that would fix the problem. Two weeks later my vehicle continued to repeat the same problem it initially did. I brought my car back to the same place,where did conducted another diagnostic and told me I need to replace the mass air flow sensor which resulted in $345.00. I was again told that this would fix my issue and approximately 2 weeks later my car not only contiued the same problems but now it will not start.
