FNB unreasonable

On the 27 I have made an arrangement to have FNB life cover debit on my new bank, then BOOM 28/09/2021, a message saying that my cover has lapsed now that when they are reinstating, they asked me a question like I am taking a new cover why the hell is that didn't your system show that I have made arrangements. When I contacted your call center, I called so many times, using the number that came with the message. When It went through, nobody spoke, but I could hear that someone was in the background.
