Norton on-line security

Hello;    I contacted the Norton chat line on 2 occasions.  After describing the issue and being assigned a case number, I was asked to contact them again once the activity code was received from our bank.    I contacted them a 2nd time to clarify we don't need assistance from them with our bank but wanted to alert them to what we consider a significant security breach.   The response I got was that they were the technical department and I needed to contact CSA TFN 844-388-0386 which apparently is a phone number for the department that pursues these matters.   Considering the situation, a pretty lame response and won't go through the effort of contacting this department.    We have had a factory reset on our computer and are using MalwareBytes so hope our computer is more secure.
