Zando online store is ******** people!!

In the last week I have placed 2 orders with Zando as they advised they were having a crazy sale of up to 80% off. I went onto the site, found items I like which were still available and obviously purchased them. A few days later I recieved an email stating that 1 item from my first order was out of stock and I was given a voucher number to purchase something else of that value. On Friday I made another purchase as it was the last day of the sale and today I receive an email stating that the item I purchased is out of stock with a voucher code. This is absolutely ridiculous. These people are ***** and they are advertising goods they don't actually have for sale. If it's happened to me twice in one week how many people are they doing this too. I am now FORCED to use the voucher and buy something else from their site. They dont even give you the option to decide if you would like to be credited your cash or receive a Zando voucher for that value. Clearly lying to people is now the new way in which Zando is making sales. Becareful of these *****. I will definitely not be purchasing from them again and would definitely not advise anyone else too!
