No Xmas gift for my son because of poor customer service

Very disappointed with the service I received this time. I placed an order on the 15th Dec and changed delivery address from my work address to home address because I’m on leave. Saturday 19 Dec the driver calls me to say he’s outside only to find he’s at the wrong address in Malvern and I’m in Evaton. I immediately called the call centre and spoke to Ammy who wasn’t helpful, gave her the correct address were the order should be delivered to but the changes were not done as the delivery was scheduled for Monday, 21 Dec at the sane incorrect address. I called the call centre again and I was advised there is nothing they can do to change the address I must go collect the order at Bedfordview myself or wait for the order to be delivered Xmas. So my son won’t have his sneakers for Xmas
