The Phone Bill and the Disappearing Discount

Here in Israel, parents who have a child with “100% disability” can usually get a small discount on their phone bill. We have gotten this, but suddenly this phone bill, I noticed that the discount was missing. An inventory of the last few bills showed that it had been stopped about half a year ago.
I understand that they need to make sure that we still need it, but I would have liked to have been warned/consulted/informed. But I guess that is asking too much…..
