No service at all

Capitec is giving me problems with money that was deposited into my late mothers account and have sent all documents and now instead of them transferring the money into my account their sending me from pillar to post. now they want the late estate account - why would I open such account when all other banks deposited the money into my account as I am the only child to my mom and the letter of authority says so. its been a month now no help whatsoever. I need that money be deposited into my bank account.
