Look buddy there was no need to put rejection letter in your file,they already have the data of every refused/approved applicant.Only difference in SPP and General is that one has to show more funds in General(22-23 lacs) than SPP(7-8 lacs).You should have prepared your file according to general checklist.Case's category does not depend upon checklist followed,those guys have your data with them,they know you are refused under SPP,you should had followed General checklist.You should have seen before on refusal letter,these lines"This case is closed now".So,there's no point in applying under SPP,as they will Check your file under general.Who is your consultant?He should have known about this fact.
Don't worry dude,SPP do not have any success rate those all are rumors about SPP,General is better than SPP.
