Telkom debiting a deceased account

After my father passed away we went into a Telkom store to close all his accounts. To our surprise Telkom send through a debit order of R8300. A call was logged with in the Telkom store to refund the family but the case was closed without any positive remarks. Few cases logged to date but no resolution still. What kind of business is Telkom running debiting deceased account? What does that say about the kind of business you do?
