Read the Label

Consider, if you will, the following email exchange:

Me: We have 3 vacancies in our care home for people with learning disabilities and/or mental health problems.
Council person: Please could you send a list of vacancies
Me: We have 3 vacancies in our care home for people with learning disabilities and/or mental health problems. (plus an attachment saying the same thing)
Council Person: I can't read the list of vacancies, could you send it again
Me: OK. We have 3 vacancies in our care home for people with learning disabilities and/or mental health problems. (file attached as well)
Council Person: I still can't see how many vacancies you have. Could you send it in the post?

Me: (therapeutic and unsent message) How difficult is it to read the fucking message. We have three (3) (III) vacancies for people with learning disabilities - are you perhaps in need of residential care for yourself?

I'm wondering what the point of sending them anything is. Clearly they are unable to read and understand the email message so why should they be able to read a piece of paper with "we have three vacancies" written on it - I'm beginning to think that the council concerned (no names but they're in West London) have some kind of special hiring procedure for giving jobs to the severely bewildered and the terminally incompetent.
