Pathetic service by Kgomotso

I called Outsurance yesterday (03/04/2018) to update my insurance details which made my premium more than two times higher. I then called again same day later to revert all the changes coz they are no longer relevant and was transferred to a guy named Kgomotso. He told me that he cannot revert my changes due to whatever reason. I asked to speak to his manager or a person responsible for such changes but he made me hold for a very long time then told me that he spoke to his manager’s manager( whom clearly I am not entitled to speak to) and got the advice that they will look into the issue and get back to me today( I have not received any communication none whatsoever) . He then continued to tell me that he is a senior advisor for a reason blah blah blah yet he was unable to revert my changes as per my request. WHY CAN’T CHANGES BE REVERTED AS THEY WERE DONE INITIALLY? I am very disappointed at the service I received from Outsurance
