Superbalist lying about stock / greedy ********* business

I purchased a project rock t shirt from superbalist when the item arrived I found that they had sent me totally different item it was a project rock vest which was not even on thier site at the time . When I contacted them conviently the shirt I had payed for was taken off site stating sold out . I asked them to supply me with an alternative project rock shirt in order to fulfill what I paid for, they declined and offered absolutely no compensation I fought this ********* behavior and they decided it was fit to give me a voucher with a minimum spend more than what my order had come to what a absolute slap in the face I argued it’s greedy and ********* . This evening I go back on site and find the shirt I ordered back in stock and conviently at a higher price point and the vest they sent me in error newly listed as well at the and guess what at the exact same price point the shirt was originally when I ordered it . The truth is they realized they had listed the shirt at the incorrect price point and as a result pulled the stock denying me the opportunity to do an exchange for what I paid for due to thier error they **** about having no stock denying me what I paid for it’s absolutely disgraceful .CPA states if an item is ordered and is in stock at a advertised price point it must be fulfilled I was denied due to their greed I have all the screen shots and correspondence to back this up disgusting really
