Changed delivery time than paid for with no notification

I ordered on Sunday night and latest delivery date if i chose Pargo was 23rd Sept which is thursday. I just checked my order status on the app the latest delivery date is now 28th Sept. By this poiny i wont need the items and also why would i pay extra to get deliver in 8days?...if this cannot be rectified to have my order by thursday i want a refund on the items INCLUDING the delivery fee. Retailors take chances with clients and you cannot simply delay my order so much. You set an expectation which now needs to be met. ORDER NUMBER ***
