"I'm sorry you feel that way" is a canned non-apology, worse than a canned apology. At least a canned apology admits fault.
I wouldn't want to get into a call with someone with that attitude. If I'm quitting because no consideration was given to me or my work, and the first response I get shows no consideration to me, my work, or even acknowledge my list of grievances, a "quick call" is the last thing I feel like getting on.
In fact, even that word, "quick", is insulting, because there's no way this is getting fixed with a "quick" call. "Quick call" implies the grievances are minor. More insults.
