I had similar with my energy provider in the UK (Octopus). For one reason or another a regular payment bounced which automatically puts you on a "call daily until the debt is repaid" list.

These calls come in on an unrecognised number, from staff who say "I don't know" when you ask them to prove they are from Octopus, and generate no call notes so you can't find out why they rang if you use the main customer service number.

To top it off they ask you to key in your card info on the phone after asking for your personal information.

I complained and they offered to fob me off with £30 credit instead of talking to their CISO, but they did at least say they can add phone passwords to individual accounts.
