MINT HOME CLEANING

I found a coupon for this home cleaner on Groupon with an expiration date 6 months after the day I found it. I called and texted repeatedly, and finally got a response several days later. I was all ready to hire him but he said that he wouldn't honor the Groupon coupon. I pointed out that it was supposed to be good through March 2019 which was months away, and he simply said that he changed his mind and decided not to honor the coupon anymore. I don't know why he did that - was his business so slow that he had to raise his rates back? Anyway, after seeing this arbitrary decision to just pull his sale price, it's a huge red flag to me about this business and I sure wouldn't touch it with a ten foot pole. I eventually found someone else with total integrity in their pricing and quality.
