What am I supposed to do to get the true Pacifist ending? I spared every monster I met but then when I got to the ending Toriel didn't come and save me like she does in the true pacifist route. I restarted my game but I found it really hard to complete up to where I got to previously.
What did I do wrong? Why didn't I get the true Pacifist ending?

To get the pacifist ending, you need to do the following:
Backtrack out of The Core so your phone works. If you have done everything you need to, Undyne will call you and ask you to deliver a letter, starting the quest for the pacifist run.
Once you have done this, return to Asgore to begin the final pacifist battle.
