I was wondering the same thing. I was denied in September. I guess my plan of waiting to reapply in 6 months isn't a bad idea after reading your experience. 
This happened to me with Walmart also owned by Synchrony. Applied in September and was denied. My score went up a lot in October and I applied for Amazon and instantly approved. Called Walmart to ask if I could apply again since it hasn't been 30 days and they told me YES! Applied and was given the 7-10 days message called right up and the rep just said I was denied.
The next day I check my reports and there is no HP from Synchrony at all for Walmart. (I also haven't received any denial letters from Walmart when I applied in September or October) They didn't pull my credit again (which would be the same in your case if you are getting the same score and you score is now different) I called back and explained. The women then told me I had to wait 30 days in between apps and to try again in 3-4 days (when it would of been 30 days from my very first app in September) she also told me if it gives me the same 7-10 day message and I don't get a HP to call right back as soon as I submit the app and then they will be able to override it.
Waited a couple extra days to be on the safe side from what the rep told me. Applied again, got the 7-10 day message and immediately called back. when I called at first the rep was confused and kept telling me that everytime I apply Walmart pulls my credit and I kept telling her that she is wrong and what the other rep told me. I told her that it's a problem with you guys and how the other rep told me to call if it happens again and you guys can fix it.
She verified my Info, put me on hold and came back to tell me she had to push my app and congrats I was approved.
Your story sounds very similar to mine. Every rep you talk to tells you something different. The first time I was told I was denied, the second time I actually got a good rep to tell me what was going on. And the very very first time I called I was told I didn't have to wait 30 days and I could apply again whenever I wanted but then told the 2nd time I was suppose to wait 30 days. She also guaranteed me that after the 30 days the computer system would pull my report again but the computer system didn't so I don't even think they know how long you have to wait between apps. Check your reports if you can and see if there is another hard pull from Synchrony/lowes. If there isn't at all call them asap and tell them the system isn't pulling your report and you need them to push the app through for you. With synchrony you have to tell them what to do and act like you know for anyone to do anything because the reps just don't know.
Good Luck and if you need any help let me know. If you don't see a 2nd hard pull like I said call them back asap because the one rep made it seem they can only override the system or push it through if you call them right away after submitting a app.
Since my approval my score has gone up almost 50 points and I tried to get a increase for the holidays and was denied. When I received my denial letter it had the same score of when I was approved and the score was dated in October
. Good Luck again OP
