Harassed

Good Day, Please note that I have a life cover with momentum for over 10 years and my account is up to date but I have been harassed by getting outstanding unpaid letters which I don't understand my account is up to date, on the 8th December I called them to asked this and the consultant confirmed that all is in order. I paid all the months And statement was also sent to me to prove that, I got another statement on 8th saying they will cancel my policy and I will loose all my funds I don't have any outstanding amount on my policy. On the 1 December 2022 they even debited twice this is really annoying me I didn't feel safe they way they're handing my policy I really need a big boss to call me. I am sick and tired and feel harassed of this unnecessary wrong statements. I don't have any outstanding months as per their statement sent yesterday all is in order the consultant confirmed that we'll.....Which month do I owe??? NONE
