Difficult to get help from 21Century's staff

On the 5/09/2018 I went to 21st Century office in Vereeniging to find out if everything with the funeral policy of my mom is up to date. I was told by Nthabiseng that everything is fine except that we were paying into the wrong account. She then sent an email to their head office to rectify and transfer the money into the correct account number. We waited for the correct account number till to date. We could not pay our outstanding premiums since we do not have the correct account number. I need the manager to sort out this issue since his/her officers cannot solve it. Every time I called, will be taken from pillar to post. Today 04/12/18 I called and was put through to Pretty who just dropped me and never answered my calls when tried to call again. Manager please come to my rescue
