I just spent a combined 75 minutes on the phone yesterday getting two separate reservations merged.
A long time ago I made a reservation on the phone for early January 2018 for a Thursday-Saturday reservation. After a period of time, I wanted to see if I could come in one day earlier, on Wednesday. I saw the Wednesday was available on-line (same level of site, both rack rates) and called in to change the arrival day. The CM said she would have to completely cancel the on-line and rebook the dates and there was "no availability". (I was holding Thursday and Friday nights already and Wednesday was open on-line, remember). So I booked the one night by itelf on-line.
Now we are about a month out from 60 day FP window so I thought it was getting time to merge them and simplify my life. On Tuesday when I tried to call mid-day, I got the old fashioned "all circuits are busy" line when I attempted to call. Huh? So on Wednesday right after breakfast (yesterday) I got through. The first 4 minutes were the voice prompts, then spent 25 minutes on hold listening to music. After 10 minutes of trying to merge, the CM realized she had to hand me off to Guest services. Another 15 minutes on hold. Guest Services guy (very sharp) understood my request, got all the relevant data, and then put me on hold for another 15 minutes while the magic happened. The last 5 minutes he came back on to recap all the details.
I think the hold times are deliberately long to encourage people to give up and make changes on-line (as the hold message during the music constantly reminded me). In my case, I was calling because I had already tried to do this on-line and failed.
Disney and I.T.
That is all.
