Pnp clothing online

Purchased 3 items from Pnp clothing online on the 10th February. 1 of the items did not arrive. I logged a query and emailed Customer Support and was informed that there was a stock issue with the one item and that they will have to refund me and that they will be in contact with me. To date no one had been in contact with me nor no refund received. I emailed them again and was informed my refund has yet to be processed and that they will keep checking. Customer support are now choosing to ignore my emails and my 2 tickets logged. Your online policy states any refund to be received in 7 to 10 working days. This has now lapsed. In addition I was not informed my email nor an adjusted invoice stating that the one item is short.
