********** Site, ******** customers for money

I ordered stuff from Wellness Warehouse early March order number:145968 which was later splits due to some stuff out of stock and new order number given:147287 and I got an email on 16/03/18 that my order has been delivered - where, I wonder... I contacted them on 22/03/18 that I have received my order and the response was that they will query with the couriers, I did not hear anything from them. I then contacted them on 10/04/18 and the response was that they are still investigating, I then contacted them again on 02/05/18 and asked for my refund and I was told that they will refund my order in full - I'm still waiting. Can they please refund my money as I am no longer interested in their products and dont want anything to with them, I just want my money bac****
