One day when you are watching your neighbor's dogs (one named Morse and the other named "nag a ram") the dog starts to have problems. Nag a ram will not stop crying/yelping and looks sad, so you decide to call your neighbor. You find the note left with the neighbor's phone number and the alphabet is also written on it, with the numbers 1-26.
You stop when it says "Aaaa AAa aa / BbBb b bb / cC Cccc Ccc c"
You are surprised at first but then you remember that you are an expert puzzler. What is your neighbor's phone number?
You need to use Morse code as @phylpy did
You need to do a step as suggested in one of the tags included.
P.S. This is my first time doing a cipher
