Lazy and Dishonest

I purchased a bag at their store in Melrose Arch. I went online to fine that there is another one of a different colour that I really liked. I searched online and found that they didn't have stock of the bag in my local store (Melrose), but there was at the Alex mall and Greenstone and threw other stores okn Johannesburg. So I decided to purchase the bag online and another two bags. 2 days later after by purchase I get an email and sms saying the bag is unavailable. So I went back online and searched the same bag and it was still available at those other stores. My frustration and anger is that they are not willing to outsource this bag from another store which is less than an hour away from the store of my choice. If the bag is not available everywhere then why is it still being advertised on their sites. Fine they said they would give me a refund but I'd prefer that they made the effort to get me the bag that my money back. The only reason I purchased the other two bags was because the other two bags looked as if they made a 3 piece set. I'm highly annoyed and realize that this store is not willing to go above and beyond for their customers - shocking and disgusting.
