STUPID staffs

Making me damn angry sia. All along, I've been with Eric at LIFE Ctr but received letter telling me to go for assessment on 19 feb to see Katherine, another physio. Called them up just now & from what I hear, Eric seems to unable to recall who am I & counter staff the way that "auntie" talks over the phone, is very STUPID!! It's actually not change of appt but neednot have another health assessment!! Simple as that, also don't understand.
