ABSA Retail Deceased Estates Department needs serious improvement

We have been attempting to have bank accounts of the deceased closed for over 8 months. I have sent several emails that have gone unanswered. Every time I have tried calling ABSA I have been waiting on hold for so long that I have given up. I just got through and was speaking to a consultant, and before I got any feedback and after over fifteen minutes of being on the line, my call was disconnected. Firstly, it should not take so long to process an account closure. Secondly, auto-reply emailing systems have made us believe that our requests are being attended to when in fact that doesn't seem to be the case. The communication has been shocking.
