I have had 2 Remingtons to date: 700 SPS Tactical and my current 700 VSSF (both 308).
SPS Tactical would not shoot at all. Maxed out windage and elevation just to get 100 yard zero (with several factory loads). Called Remington and explained what was going on. They told me I had to write a letter explaining the issue with the rifle, place rifle in factory box (or plastic rifle box) along with the letter, and they sent me a call tag. Sent rifle in, and 3 weeks later, the rifle was back in my hands with a new barrel.
Rifle still would not shoot past 100 yards. I did not know a lot about rifles (way less than I do now, and I still don't really know poop). Sold the rifle because I did not want a 308 caliber 100 yard gun. Guy bought it, put on a HS Precision stock, and it drove nickels to 200 yards. Pretty sure it was just the stock that was crap.
Bought a 700 VSSF in 308, dropped in a few handloads I built for my savage, and it runs 3/4" at 150 yards. Bell and Carlson stock, full aluminum bedding block, older adjustable trigger (Rifle was built in 1996). Safe queen as far as I can tell, and she is a shooter.
I did not have a lot of complaint with my SPS except it would not shoot at 200 yards and further. But, I think that if I had taken some time and learned, that may have been a good rifle.
Remington customer service has been good to me. One bad CSR should not dissuade you from buying again. We are all just people and have bad days, especially when customers "want a supervisor". I have been on both ends of that call (the CSR AND the supervisor). It is not a pleasant experience, mostly because all the calls you get are ****ed off people. That is a hard job to do and still treat everyone 100% everyday. Just the way it is.
Just my two bits...
