POOR SERVICE, partial delivery of online order, no communication

I placed an online order with Game stores, one of the items was a TV. I emailed the TV licence to the address provided but the order remained on hold until I phoned them and resent the TV licence details. Then I received an sms stating that the courier would contact me to arrange delivery, this did not happen. After the weekend I contacted them and was told the order had been escalated and given reference no: ********** 4 and told a manager would call me (still waiting for that). Monday evening some items were deliverd except for the TV, foldable dryer and broom set. What do I have to do to get my full order. The service is appauling, I would not advise ordering from Game to anyone, they do not even communicate with the customer when there are problems, the reference number is just a show
