Trying to add a customer with a number in the name treats it as the same customer

[emzm2023]

The app behaviour is as such when I tried to execute the command seen in the command box. Given that the restriction for names is that: "Names should only contain alphanumeric characters and spaces, and it should not be blank", John2 Doe should not be treated as the same person so the functionality of the app doesn't seem to be in line with the given constraints in the UG.

Team's Response

It does not violate any of the constraints stated in the UG for both name and phone number. The reason why you are seeing this error is because it has detected that the phone number you have inputted already exists as we use phone numbers to differentiate between different customers.
