STANDARD BANK BAD "NON" SERVICE WITH REGARDS TO ESTATE

I cannot believe the "non"service received by us with regards to my Dads Estate. We have been trying to resolve this for over a year now and now, emails are going UNANSWERED!!! Sent complaint to Standard Banks Resolution Department and that has ALSO gone unanswered. There are no words to describe the stress this has caused my Mom after my Dads death.... We are changing HER Will and moving away from Standard Bank as this is unacceptable. With such delayed bad service I dont know if we have any way to NOT pay them their "fee" for handling the Estate. I could have done a much quicker and better job myself.... Please if you have any WILL with STANDARD BANK I suggest moving them.... We cannot even march into a branch as done in JHB and not CT....
