Account breaches

I called in yesterday to the tech team as there was an issue with the router. The account is not in my name but they were able to assist me in deleting the entire Mac address and setting it up again over the phone, WITHOUT SPEAKING TO THE ACCOUNT HOLDER. Today I changed banking details and this was done WITHOUT SPEAKING TO THE ACCOUNT HOLDER and after all of those breaches which I was told this evening by a manager is not suppose to be done (bear in mind I changed the banking details with a manager today and the manager didn't speak to the account holder).

All I want is a password reset on the adsl line but after all this major breaches, this cannot be done. Bunch of bull**** and the manager still had this nerve to drop the line on me as well
