Levante urban hasn’t delivered

On 7 July I purchased on line at Levante urban and received my invoice on 9 July I got a message for the courier guy that my order was cancelled. I called Levante number which doesn’t work I sent emails they don’t respond to find out what is happening. I called courier guy he informed me the delivery was cancelled because the was nothing to collect. I have sent email again to Levante with no response. I want my full refund. Till today 14 July no delivery no communication n no refund
