Operators should not be able to change phone number when issue was submitted by app

If operators change the phone number, which we have verified, the app looses track of the issues reported by the user.

They're frequently changing the data to remove 255 and include instead a zero.

This should be masked when they insert values in this field.

When they do that, you lose track of your requests
solution 1) do not allow to edit phone number
solution 2) when you query, send both results for 255xxxxx or 0xxxxx
