Incrediable connection - Items not delivered to delivery address

On the 29/11/2019, i placed and order online with Incredible Connection for delivery at my work address between 8am-5pm. On the 02/12/2019 at 05:23, i got a call from the courier service to say that he was at the delivery address. I told it was after 5 and he needed to return the next day. He told me he would leave the item at the Bosch service centre and then cut the call. My delivery address is at 1 Groom Street Verulam and was at the delivery address from 07:30am - 05:10pm. The Bosch service centre is in the same vanity of my delivery address but it is not the same address. I called customer service to report the matter, I told by the customer care consultant Dudu that a complaint would be lodged and reference would be emailed to me. After 3 hours and no reference number, i email Incredible Connection internet sales division. Its been a day an I have received no contact from Incredible Connection and further to this I don't have my orders. The courier service and customer service have a don't care attitude. Why continue to host an online platform if you cannot provide the service to the customer. I am very disappointed.
