How long for a pip decision

Hi poppy thankyou for that advice i did not get enhanced for both wich i found odd i got 19 points for daily liveing n was given medium rate and i got 12 points for mobility and got enhanced rate for that..verry strainge i sent my review forms back 8 months ago rang dwp last week and was told im in a que waiting for a telephone assessment,also i have seen posts on here that the assessors lie how can they write that someone could walk into the assessment center when they had a telephone assessment..it makes me wounder if they are reading someone elses forms
