Checkers 60 app *****s your money

Another retailer that takes your money, and doesn't deliver. I tried to use the 60 app this morning, after having to restart the app several times as it kept getting stuck and closing, I managed to place an order. I then received no notifications and eventually an email to say the driver was outside, so I look outside to see him driving off and now my order is canceled. However, they have not refunded me nor rep**** to the 2 emails I've sent to their help Centre. They just ***** your money, blame the customer for their own iniquity, and then ignore you.
