Appalling & Disgusting handling by Game

Absolute worst customer service ever!!!! I bought a Christmas gift for a 7year old on the 20/12/2018 through Game online store and by the 02/01/2019 the item had still not shipped out. I called their contact center to query this and was told the item had gone out of stock before Christmas?? The agent said they'd look into it and contact me back. I waited 4 hours and called them back to get the same agent tell me she had actually already spoken to the warehouse and they would be dispatching the item but couldn't give me a set date. I emailed in to cancel on the 3rd and called the 4th to confirm the cancelation of the order and I was told the refund would be processed in 7 working days. On the 7th I received a dispatch email from Game saying the items have now shipped out. I called their center back and was told there was nothing they could do, I would have to call the recipient and ask them to refuse delivery.

HOW DO I TELL A 7 YEAR OLD THEY'RE NOT GETTING THEIR BRAND NEW BIKE ANYMORE?????

Not only did I get them a replacement gift but now they got this too after I was told it was cancelled!

Game has been absolutely appealing in dealing with this. Never using their services ever again!!!
