Unauthorized and ******** double debit on my account - to be refunded

I am deeply aggrieved by Rain telecommunication in partnership with NuDebt, i made an arrangement to activate my WiFi on the 31 July 2023, the agreement was they will deduct from my FNB account of R1100, which they did, and upon checking my balance i realized i was double debited R1100x2 = R2200, first deduction was effected on the 31 July 2023 as agreed and on the 1 August they deducted another R1100-00. I called them to refund me the money but they keep denying they deducted the money twice, i was asked tp prove it by emailing them my bank statement to ***. I have since been making follow up for my refund but they keep telling me the deduction is only once yet my statement confirms that. I asked to speak to a senior person by the name of Elaine Jerk every time they transfer the call it cuts me off. I have spoken to a number of people namely, Noluthula being the first who arranged the deduction, secondly Kefiloe, Shondile, Renee and Siya, all tese people could not assist me to get my refund. Im tired of talking to these people they simply dont want to refund me. please intervene before we escalate it further, need less to mention the horrible treatment i got over the phone.

Kind regards Patrick Dubazana ***
