Pathetic service from 2 Capitec branches

My name is Thabile, my sister who was a Capitec client passed on and I was the beneficiary.

On 23/08/2021 I went to Capitec in Lenasia branch to sort out her finances and the consultant Mbali told me that she need to request the Bank statement from Head office and they'll call me within a week. After a month went by nobody contacted me, I went back on 21/09/2021 and spoke to a different consultant who appeared to have more knowledge she even scanned all my documents(Letter of authority, Death certificate and my ID book) and promised to call back in 2 weeks unfortunately she never called back. I then went to Maponya Mall branch 05/10/2021. I told the consultant Palesa about my previous experiences from Lenasia branch and she promised me a perfect service and I will receive the Bank statement within a week since this is an existing query however I'm not being contacted till today.

I need assistance as we know that she had fixed her money with Capitec Bank.
