This mixer kinda has high fees compared to their competitors, any chance you guys lower the fees?

I used to be in the bitcoin core crowd but after still paying ridiculous fees recently Ive moved over to bch and SV, I Guess this is kind of a rant, but I dont understand who the hell wants to pay high fees to send money to someone.

Don't tell me to upgrade electrum. I'm aware this old version has problem but I'm using an old laptop that can't download the new version.  I only use this laptop to play runescape and I only keep $50 or less of btc on it to buy runescape gold.  I had no problem using 2.9 version of electrum until a few days ago,  now it just is stuck on synchronizing...

How do I fix this without upgrading versions?
