Terrible Online Order Experience

<p>I made an order on the app on 13/01 for 3 items, order was confirmed. Received an email from Michellene on Sunday 15/01 to advised my order ( ********** 16831) was cancelled and the reason being all 3 items were out of stock. I checked the app and all items were still showing available, when I queried this Michellene advised that the system hasn't updated, that they are out of stock. I decided to just try and re-order 2 of the items on the same day that my other order was cancelled, and my new order was confirmed and by the next day it was shipped. So I want to know why Michellene cancelled my order in the first place when the items were clearly still in stock and caused me this inconvenience, because I've had to reorder and still do not have a refund for my cancelled order? I've emailed MrP Customer Care and had no response, I tweeted them and the response I received was pathetic. They just apologised for the inconvenience but did not advise why my order was cancelled and why Michellene ****. When I queried this, they responded with 'the agent did advise that the order was cancelled because items were out of stock'. This shows that even your customer service agents don't do their jobs properly and don't read our complaints! Because I clearly explained that the items were still in stock. How am I supposed to be reassured that this will not happen again, how can I trust purchasing online if this is what happens, and I purchase my stuff mostly online. I'm really disappointed by the service received all round. And I would like my refund urgently for the above order.</p>
