Bennys Smog Check Tested a car knowing it would fail, wouldn’t honor retest. Rialto California

I took my vehicle in to get a smog test done. He came back about 5 min later saying that the check engine light was on and that he failed it and I had to pay the fee. He said I could bring in back to get retested after I got it fixed.

I went to retest and he said I had to pay full price even though he wrote down that he would retest for a different fee. He would not honor his promise and I believe he intentionally fails cars to scam people. People in front of me were mysteriously failing too. I've never been to a shop where almost every car fails.
