Auto&General deny receiving my payment

Received a sms & email from Auto & General saying that my debit order was unsuccessful and I might no longer be covered. According to my bank statement it shows that the debit order was successful. I then went further & visited my bank which also showed me that the debit order has indeed been successfull on 30 Jan 2021. I call auto & General on 15 Feb 2021 @ 12:02pm after receiving the sms and spoke with a consultant Tevin Edwards whome confirmed that the debit order was successful. Please replay recorded call. Today I received yet another sms & I called yet again at 12:08pm 17 Feb 2021 & this consultant says its has been unsuccessful. Also note that the bank statement has also been forwarded but since there has been no feedback. I have had it now with your call center and having to spend time sorting this out. I need feedback as soon as possible as to what happened to the payment. I have provided proof of payment.... Why can't this be sorted. Did I make a mintake choosing auto & General as my insurer.
