Unauthorized debit order

I joined Clientele on 20/10/2020 and asked the guy that assisted me over the phone to run the debit order on 25/11/2020 and he said it's fine. To my surprise. On Monday 25/11/2020 I saw a debit order of R466 taken out of my acc by your company. I sent an email on Monday and got a response to give you 2 working days to get back to me of which you never did. I sent another email on Thursday and got the same email. I called into your call center and asked to speak to a manager and the manager advised the agent that he will call me back. I told the agent to tell the manager that i have been waiting for a call since Monday therefore I do not want another promise that will not be honoured. The manager by the name of Vernon came to the and said he will speak to the billing department to confirm the payment and then process a same day refund and said he will call me back before the end of business yesterday and he never did. I called again this morning and asked to speak to him. I was placed on hold the agent and she came back and said Vernon said he is busy with my refund and will call me back. I told the agent I don't want another promise of a call back from him because he did not honour his promise. He finally came to the phone and said the refund will be in my account between 12 pm and 2 pm and nothing came through. I called again at 16:56pm and an agent by the name of Toso pretended that he couldn't hear me when I asked to speak to Vernon and quickly said "I'm sorry I can't hear you,if you can hear me please back on 011" and then hung up on me. I called again and got through to Siphiwe and told him I want to speak to Vernon.He placed me on hold to get Vernon and he came back saying Vernon is in a meeting and that he asked him to help me with my query. I told the agent that he must Vernon that he must comes speak to me because there is no meeting at 5 pm when it's home time.After being placed on hold again he came told me that my money was refunded back in their side and that I should take it up with my bank. My question is why should I take it with my bank when it's Clientele that debited my account unauthorized. I also complained about the agent that hung on me and he only said he will escalate it to their compliance department. I must say for a "Customer Service Manager" to be using words like "like I said" to a customer who needs assistance for an error caused by your company is very disappointing and appauling. He was not courteous all. The only this that comes out of his mouth is lies to try and get rid of you instead of assisting. I have spent R90 on airtime trying to call you to get my money back and I would like that to be reimbursed,my bank charges reimbursed and my policy cancelled as I do not want to do business with a customer that is *********** and dishonest to their clients.
