Assistance with changing delivery address if not please refund I reorder

Order number ***: I made an order online yesterday as I am a biggest customer at Mr Price, you can check my history through my ID when I do laybyes and buy online. Yesterday I mistakenly selected a wrong address for delivery and that was after I confirmed my order. I quickly sent an email to the Durban Warehouse Department, went on Facebook inboxed my request to change the delivery address and also went to their "live chat" on the online app to ask for assistance and unfortunately there was no response. This morning again I sent emails that's when I got a response that they can't assist me with changing the address to be delivered at Motse Wa Lejana Shopping Center Mr Price. It pains me that East Rand Retail Park is far away from me as I would like it to be delivered closer to cut the costs as that it was the aim from the beginning. If that cannot be done, can they please refund me I will pre-order because this is unacceptable honestly. Please give me a feedback.
