What a frustrating journey to experience with my double debit

What a frustrating journey to experience with my double debit. I got double debit for Dec 2021 since the 3rd Jan been calling in for assistance and i am being sent left and right and centre. the level of unprofessional staff you have is very disgusting. i need to escalate the matter in order to get help from your finance as this is going on for 2 weeks now
