I recently upgraded my phone to the Samsung intensity, and I'm horribly frustrated. My USB cord does not work, I can't set individual ringtones to individual contact ids, I can't copy music to my phone, etc. I've called customer service 4 times, including a PROMISE to get a return phone call (which never came), and went to the local store twice. I tried to get the USB device drivers by download from this site- no such luck. I'm so very disappointed, and also p-o'd, with the service I'm getting. Anybody else have the same or similar problems? And how did you get it handled? Is it because I didn't want extra internet for my phone? A bad USB cable? Or just too much stupidity on my part? You'd think the phone would have come with step-by-step instructions, but of course not.... Any ideas or suggestions would be GREATLY appreciated!
