I've done several recorded calls, and twice they disconnected before the call was over. With one, I was able to make the call again, as the MSC allowed for 3 tries, each with its own code. They were able to catch both calls.
On the other one, there was no way to re-try the call since the first one would be recorded over, and there was no need to repeat the initial inquiry all over again. It would have been really weird. But if I'd been able to say, "I was just talking to you about carpets and we got cut off...." That way the MSC could have had the entire conversation.
So, I do think your experience wasn't the norm. Maybe the system was glitching, if you and your wife both had the same thing happen.
I learn something new every day, but not everyday!
I've learned to never trust spell-check or my phone's auto-fill feature.
