Monro Auto Service Replaced catalytic converter Pittsburgh PA

My check engine light was on and they told me it was a bad Cataylic Converter. The assistant manager called and quoted me a price, which he did not say was for an aftermarket replacement. Then the next day the manager called and told me that the price would be higher as my 2014 Silverado required an OEM converter which they did end up replacing, however they replaced it with the aftermarket one. When the light came back they told me they could not find the problem and advised me to take it to GM which I did who confirmed that the light is on due to the AFTERMARKET converter as my vehicle requires OEM to fix the issue.

When I went back to Monro they told me they would replace it with the OEM, however after 4 days sitting in there shop they did nothing besides clear the code. I thought something was up when I went to pick it up they rushed me out the door with zero paperwork and stating I was good to go and there was no charge. After 2 days of driving my check light came back on and I confirmed that I still have the aftermarket converter installed on my vehicle.
