MacDonalds haven't replied to my application yet?

Well I sent in my application to MacDonalds over metime because i'm looking to get a job, they say that I will be reviewed of the outcome within 72 hours and it has now been a week, this is annoying because its not the first time i've sent one into macdonalds using metime and it took them 3 months to reply just to tell me I didn't get it.. how long will it take them
