i've come across this problem twice in the last week..
i'm given a phone number to call and it's a combination of numbers and letters.. and i can't figure out which numbers correspond to which letters!
during another call, the automated service asked me to input my account number, which consisted of both numbers and letters, and again, i couldn't figure out which numbers to press when it came to the letters!
anyone else have this problem? is there a quick solution?
