Policy lapsed with out my knowledge

I am very disappointed in the treatment I received from ABSA bank regarding my flexi funeral cover, I called absa and advised them I had to change my bank account so my debit order should be moved to my new bank account last year January 2016. I received a letter last week stating my policy had lapsed and it's been cancelled as debit orders did not go through. <br> <br> Please tell me how the HELL did that happen that because I called ABSA in time and advised agent to change my bank details and she confirmed they were changed and the next debit order will go through from my new account. Now it's cancelled should any of the people insured die GOD help me coz I won't have any policy active as you guys cancelled.<br> <br> I need someone to call me back as soon as possible and tell why is it cancelled and who will rein staid my policy and I won't wait for any waiting period. <br> <br> My number ***.<br>
