change of oil

The owners/administrators and quality of service is HORRIBLE. They are the most RUDE, and unpolite people. They are not interested in helping the customers or keeping them !!! ANYONE MAKES MISTAKES, BUT THE HORRIBLE AND RUDE TREATMENT IS UNNACCEPTABLE. Went for an oil change and the mechanic forgot to put new oil. They said it was ready and I Drove away and two blocks later my motor broke down. It turns out they never replaced the old oil and instead left my car empty!!!! I had to go back and the owners were so rude. Especially the old lady in the front and uncle of the owner/ the administrators !! They never apologized or were willing to help even if the mistake had been theirs. The mechanic realized it was his mistake and wanting to fix it ! The owners wanted me to leave and insisted that I needed to leave that they didnt care and they needed to close. What was a 15-20 minute oil change turned into a whole day where I lost my working day, was never offered water or help, and was kicked out.
