Discount Auto Repair Oil change without changing the oil filter Hillard Ohio Ohio

I went to the Discount auto repair shop On 4557 Scioto Darby Road on Febuary 1, 2017 to get an oil change. I checked my oil filter before going in and put a line in the grime on the end. After the Oil change I parked the car and checked the filter and observed it was the same dirty filter still on the car adfter fresh oil was put in. I called the company and the guy explained their tech was new and he would have to be trained better. It was about a year ago when this same guy was working, when I observed him changing the oil in the car in front of me, and I could see him under the car and he did not change the filter on that car. I confronted him and he acted appalled that I suggest such a thing, but also acted very nervous in explaining. He even showed me my filter after that. I quit going there until a month ago. There was another younger bearded guy, that always did his job and changed my filter each time. It is when the older gentleman isworking when these two occurances took place. The older guy did do the work today a new guy was with him.
