You can ask them to put your DSL account in an online gamers poll, where your modem gets an IP which has good latency,
I don't know if they have some new technique for online games,
you can suffer from high pings sometime and that would be mainly in the peak hours i think, (where you have some congestion on your central "that what IDM Support always say during slow downs" ) maybe between 5 PM - 9 PM
I didn't call the support since Nov 2016...but is there any actions for performing our pings to even better results ?!
I did not know about the gamers poll? Is it free?
As for the slow down time from 5pm to 9pm, I'm facing similar issue and decided to investigate it, I was watching the SNR value at this time, the problem was it was getting very low in the time period you mentioned, so I started to cut down the power and test when the power was down at 12am, the 8.5dB SNR value increased to 11dB when I unplugged the UPS from the socket next to the phone line, and also increased to 16dB when power was down!
I believe at this time of the day the power usage gets higher and because the phone line is installed in an inappropriate way, the interference from additional power usage even from your neighbors will cause a high noise on the line.
I'm looking into ways to fix this and ill report if I still face slowdowns.
