Drained to the core by ****mers

I feel drained by the bank I have been with for more than 10 years, I complained here last week thursday regarding Capitec app which was malfunctioning, I bought electricity via the app and it kept on saying I must try later, little did I know I'm trying later while they are debiting my account, I have lost about a 1k with this ****mers, they called me once and told me they are investigating, to this day I am waiting, no update, my money is gone and I still do not have electricity.
