Awful Jet

My mother had a Jet account for years. But she stopped using the account but kept it open because she had a funeral policy. A few months back we learnt that there were covers that were added without her knowledge. The agreement was that Jet was gonna cancel all policies. She was called last week and informed that she owes R1200. She went into a Jet store and was transferred to numerous departments but seemingly no one could answer where the R1200 came from. I have concluded that Jet is ****ming its clients. Jet wants to kill my elderly mother because all she speaks about now is how she feels defeated because she can't seem to get answers about how she owes so much money when she was paying for the funeral policy. Also if Jet now works with RCS why aren't they catering for their old clients. because it seems like Jet workers don't know where to escalate client issues.
