Non delivery but paid cash for furniture and delivery fee.

Made an order on the 3rd for a wardrobe and headboard and was advised delivery will take 3 to 4 days. However I am still waiting on my order. I had to call and was advised it will be delivered and i should've received an sms but nothing came through. Waiting a week receive my order paid cash is absolutely disappointing. I just need to request my refund at this point.
