Have you contacted Customer service staff at any time with your account?
Be mindful there's been arrests made and closing down of Business Process Outsourcing (BPO) in McKinley West, Philippines in recent times because of unlawful behaviours relating to ABB.
It pays to keep an open eye out on International news about these places because there's some serious offending and failures to comply with basic laws going on in them.
May we suggest you obtain a Data Subject Request of your account and go through it with a fine tooth comb.
Any unlawful access / compromise of your account should also be reported to your local law enforcement agencies as often matters are not isolated incidents.
All the best.
