Overselling - delayed delivery despite stating they have stock

<p>Placed order yesterday 2nd of March, paid and got delivery date of the 6th of March. Still had one unit in Stock on the site afterwards. This morning I get notified that they don't have stock and I now need to wait until the 15th of March for delivery. What happened to the stock? Oversell it and now making it my issue. Not Happy with this at all</p>
