Pay back my money

On the 23 March 2023 I canceled my policy with Dialdirect(***). Unfortunately it was too late for them to stop the debit order for the next month. On the 25 of March full premium (R2972.08)was deducted from my account. I then called Dialdirect requesting them to refund me and the lady told me she has processed my refund and it will be deposited into my account within 7 working days. Three weeks down the line my money was still not paid. I called in again and I spoke with Ntokozo. He assured me that the money will be in my account within 48hrs. On the 19 May 2023 I called in again and I spoke to Kopano. She told me my money was paid into my account on the 3rd of May 2023. I told her that no such payment was made into my account. She then requested me to send her my bank statement via her email address. I immediately sent her the statement as requested. So far I haven't heard anything back from Dialdirect an my money is still not paid yet.
