pip help please

hi everyone, i had my telephone assessment a couple of weeks ago,  i rang dwp on friday because i hadn't received a text message to say they had received the report back from assessor , and also to request a copy of the report. the lady took all of  my details and said " oh its all been done , was done on wednesday" !  i asked what she meant , she said "it looks like there is an award, a letter has gone out today"(friday).   she then said she couldn't view all of the details to let me know what i was awarded , (something about 24 hours,the system wont let her) and to wait for my letter. has this happened to anyone else ? can someone please advise me on why she couldn't see the details  of the claim ? is it normal they don't give the details of award over the phone sometimes ? very sorry for a long winded post, but it just seems odd, any help or advice would really be appreciated.
