Hi I Need Help Please. My New-style Gmail Account Is Not Functioning Properly.

IT'S ALL TAKING FAR TOO LONG AND I WILL HAVE TO CLOSE MY ACCOUNT VERY SOON. WOULD PREFER TO RETURN TO OLD STYLE PLEASE IMMEDIATELY: 1. Scrolling down list takes forever! 2. Scrolling down inside an open email takes forever and jumps down in great chunks after waiting minutes, then jumps back up in same fashion 3. I cannot return mails, I have to compose a new one every time! 4. I cannot forward any emails on to others. Please help by return. I am not good at IT so will need careful guidance please. Can I call a free phone number in the UK? Best regards Jane De Lacey
