Promiseds but Lack of response

I bought a bike on Friday (23/10) and I asked that it should be assembled I was promised by that I could pick it up on Monday. I went there and was informed by Kuben that it was taken to their warehouse and that they will request it and Ill get feedback from them. It's Thursday today and still no bike I went in yesterday (28/10) spoke to Maxwell and was promised that I would get feedback today still haven't received anything. Now I've been calm about it but now I realize that Game is just not delivering! my son expected that bike on Monday and he still doesn't have it!! I'm really angry at the way Game is treating this situation especially since there were no issues when it came to paying for that bike! Please can I have feedback and not to tell me that its being requested from your warehouse -since you have clearly failed in that - but to tell me to come and collect it! Because frankly this warehouse running around is not good customer service
