ACCA FR Practice and revision kit BPP

Hi ,

I bought revision kit from BPP using 20% discount code from this website but I cannot access both ebooks from app and website using same log in detail as when I bought online . I already email BPP but they never reply until now. Did anyone bought from BPP before ? Should I request for cancel and buy from Kaplan revision kit instead. Kindly advise me. Thanks.
