Kerala Water Authority — rude behavior of collection executive

Hello,
The guy who came today for the collection threatened my mother claiming the meter isn't working and if you didn't get a new meter by tomorrow, he will come and cut the connection on the other day. And when we change the meter make sure to place it on an easily accessible place so that he can go and collect the data without any hurdles.
Is this the way a govt servant should behave to a senior citizen.. My mother is handicapped also. At first, we wouldn't get any idea if the meter is faulty until you guys give us a warning.. He could have suggested.. Instead the behaviour was rude and bad. This the first time we are having such an incident from a govt firm. So sorry but i think this should be informed so that it never happens again. Thank you!
