Can people in you claims department read?

First, they didn't read a email stating when my son's follow up appointment is with a specialist and i had to complain to get that sorted out.<br> <br> Now i send in a claim and they can't read the invoice correctly? How do you put a claim through as R.00 instead of the R700 clearly shown on the invoice and that ia after receiving a claim submission email stating the correct detail for the claim.<br> <br> Send your staff back to grade 1 to learn how to read.
