Did you get the letter from undyne after befriending her?

Go back through the Core back towards the MTT restaurant.

Undyne will call you.

Take the letter to Alphys' Lab and you can slide it under the door. You'll go on a date with Alphys etc etc... True Lab.

After you get the letter from Undyne, you head over to Alphy's lab, slide the letter uder the door and then you'll go on the date. After that, you get a call from Papyrus, and he'll tell you to go to the lab. Once you walk in, there will be a letter on the ground telling you that 'she wants you to learn the truth' and you walk through the door that was supposedly the bathroom.

I keep doing that but Undyne still doesn't give me the letter. She just keeps saying "ACHOO!" etc, etc. She doesn't call me either. Just in case I did something wrong, I went to the MTT Restaraunt, and when I didn't get a call, I went to the CORE and went BACK to the MTT Restaraunt- Still no call. Please help.
