Triple Debiting Accounts

Good Day<br> <br> We have had Liberty Insurance for more than a year now and recently we changed our banking details.<br> <br> Since then my account has been debited three times with various amounts but for the exact same service.<br> <br> Liberty then took more than one month to reverse those charges and then to my surprise, after all the forms and the waiting and not to mention all the bank charges incurred on my side, Liberty charged my account again not once not twice but three times with once again two different amounts.<br> <br> This not only happened to me twice but to my brother however
