Astronomical waste of money

Received a 4 page letter dated 20th Feb 2020 from DWP to inform me my payment is to increase by £1.90 per week from 10th April 2020 due to change in social security benefits. I have since received two more identical 4 page letters dated 6th March 2020 and 17th March 2020! I dread to think how many of these have been sent out and at what cost!

I would keep it until the current crisis has abated and then report it to your MP. Duplicate letters must cost a fortune and are constantly happening.

Another identical letter received dated 23rd March 2020, that's the fourth! Is it just me that's getting these duplicate letters?
