shocking service recieved

Believe it or not I have been paying insurance premiums on my wedding ring for the past 21 years and Standard Bank have never had a problem taking my money every month but now that it has been lost/****** I have been messed around since the middle of July trying to sort out payment for ring. I have spoken to agent after agent - then eventually insisted on speaking to a manager who promised to call back the following day well that was about a two weeks ago. Am truly at my wits end and cannot believe that this is the kind of service we should be accepting in this country. I am frustrated and infuriated and would like to move my insurance elsewhere right now.
