Poor service

Absa collections Custom Management is useless, I was incorrectly debited 3/4 of my salary on the 28.05.21, I spoke to 7 different people as from the 01.06.21 all of them said a refund will be done in 2 to 3 working days, after 3 working day I went to the branch in Norwood the manager also promise the money will be refunded in the afternoon, on the 14th I went to their Rosebank branch the also promise the money will be in to my account the very same day, until today. I'm starving because of their poor service.
