Mr. Efficient is NOT a reputable business!

Mr Efficient is NOT a reputable company!
I purchased two vouchers through Kahoot.ca to have my cars cleaned by Mr. Efficient.
I actually called them before I even bought the vouchers to verify that they would in fact drive to Kemptville to clean both cars and their answer was a definite yes. So I proceeded to buy two vouchers.
I spoke with Noreen from Mr. Efficient 3 times throughout April and May and was never informed by them that they would not come out to my home to clean my cars. In fact we made two different appointments.
This morning my husband stayed home and they were supposed to be here at 10 a.m. to clean our cars and he called me 10 minutes before the scheduled appointment to say they are not coming and he doesn't care that we bought the vouchers and he told us to just call Kahoot and get our money back.
I told him that he never informed me in the 3 times that I talked to them before that they would not honour the vouchers, why now?? Why 10 minutes before you are supposed to be at my home???
I have also let the BBB know what kind of business they are and I know for a fact I am not the only one who is having problems with the company Mr. Efficient.
