No delivery/Was sold product thats out of stock!!!

I bought a perfume set on the 18th of September from groupon and when I had not received it after 14 working days I started to call them to inquire. I literally called almost every day for 2 weeks just to get an answer about my purchase. So they finally got back to me and said that they would have to give me a refund (which I'm waiting for) and when I asked why they said that the product was not in stock and they don't know when they will have it. The thing is while I was on the phone with them I decided to check their site to see if the deal was still on cause when I bought it, it was going to expire in 2 days from then and strange enough they had re-advertised the deal. So, I ask the lady why they advertising products that they cannot deliver and she says they are allowed to do that. As far as I know, Bait marketing, the advertising of products that are unavailable as a ploy to attract consumers is prohibited by the consumer Act. So, why is groupon running a promotion if they are fully aware that there is no stock available??? This is unprofessional and very disgusting!!!
