More carriages are needed on the Reading/Windsor and Eton Riverside -Waterloo service!!!

Why are there so few carriages on the Reading/Windsor and Eton Riverside to Waterloo Line every morning?? I never get a seat in the mornings; the train is constantly over-crowded, and I’m always packed in. Why aren’t there more carriages on this line? Your staff can surely see there’s not enough. I loathe that I have to travel via South Western anyway; the strikes and the delays and the completely shambolic way you have run things in 2018 are an absolute joke, and I can’t even get a seat on your over-priced, badly-run, pathetic attempt at a train service! Why are more carriages not put on to at least commissarate how bad everything else is on this service?!
