Disgusting service

I called Absa savings and Investments last week Tuesday as my savings account reached maturity. I was asked outdated security questions of which I failed. My account was blocked and I was told that a consultant would call me by the next day. To this day I I received a miss call only yesterday. I've been following up every other day but no one can assist me and I just receive emails that my case has been closed!!! Surely if you call a client and the call is missed on one particular day, a follow up call should be made. I'm so disgusted with Absa's service
