Edgars service shocking!!!!

I did an online purchase on the 6th of May. Had to keep phoning to find out where is my order. Being told that my order was being packed and sent for delivery then to be told only half my order is available... I have asked for refund which I was told would be 5-7 days... still waiting never getting any feedback from them. First time I buy from them online... shocking service!!!! Where is my refund????
