Unauthorised debit order and poor customer service

9May2023 unauthorised money debited from my account,phoned on 10/5/23 and was assured of a system glitch and funds would be in my account by latest 11May2023. 11May boom no money and I phoned again, spoke to Taryn Fredricks who promised it would be escalated to her manager and she would give me feedback and phone during the course of the same day, Taryn never phoned. Today 1/ May 2023 I spoke to Quma who tried getting hold of Taryn for an update as there is no evidence in the computer/system that she escalated the matter, boom they unable to reach Taryn. Matter is escalated but I feel this is such unfair service how much would you guess I spent of airtime with all these flippen calls? I’m thinking of changing banks!
