FNB Life disgusting service

I took a life cover with FNB years back. They terminated it in September 2019 and the issue was with them not collecting premiums. I called them and they re-instated it. I noticed again in October 2020 that they did not take the premium from my account. In November 2020,they did not take as well. I called them to find out what the issue was. They consultant I spoke to did not have answers so she offered to contact their IT department to find out the reason for non-debit. She told me that she would get back to me by 5pm on the day. This was the 3rd of December 2020 and to date I bave not heard from her. I sent an email on the 9th of December as follow up and still have not received any response from that. The service at FNB life is horrible. I cannot keep calling every year over the same thing and there is no response. After not collecting these premiums,you will cancel my policy only you will benefit from my premiums because you will not refund me even after the horrible service you are offering. Please attend to my query or if life cover is not working for you guys,pay me back my premiums and I can find another house to insure with without this much hassle
