Bad service from Game

I bought a Zodiac Combo Pack online on 11/12/2022 (Ordered Number: ***). It was to be delivered via the courier company on 15/12/2022. When the courier company arrived 15/12/2022, I was not ar home and the courier company advised, via SMS, that they would try again. On 15/12/2022 I also received an email advising the following :

"These products have been cancelled and the items are being returned to the source. You’ll be refunded the amount for this order"

The courier company did try to deliver a second time, but I was not at home and I advised them to please send it back as I had made alternative arrangements in light of receiving the above email received from Game Customer Service. I understood that the item would be sent back and I would receive a refund. To date, I have not received my refund. This is after three visits to Game Vincent Park, East London and also a phone call to Game Online ***) on 16/02/2023 at 09:13 and I spoke to Tara who advised that she would get back to me the same day. I am still waiting for that phone call and also my refund and it is now 18/02/2023. Very poor service from a large business.
