Dizzee is still immature, let him diss Wiley if he wants. When he gets older and matures he will regret airing and dissing Wiley because Wiley has shown nothing but love since day 1.
Ever since he sold himself to pop Dizzee is in that childish mindset where just because he is doing well, he will do everything in his power to "show off" to Wiley in an attempt to make him feel like crap for whatever happened in ayia napa.
Truth is, Wiley apologised several times and continues to like Dizzee. I mean, I don't know what happened in ayia napa, but no matter what happened, you should always accept an apology if it is genuine (which Wiley's was). Always accept a genuine apology but that does not mean you have to be friends with them again. He should of accepted Wiley's apology and then left it at that. But instead he does the childish "hmph" and spits his dummy whenever Wiley shows credit when it is due.
What I am trying to say here is that Dizzee is being a baby about the whole Wiley situation and needs to man the fuck up and just accept that Wiley has (finally) stopped caring about Dizzee, but is still open to a friendship if Dizzee is up to it.
EDIT: also a very sub-par track IMO.
