Closed account still receiving payment requests

On 31/7/2015 my father,Prof SPC Swart, died.On 27/8/2015 we visited the Menlyn branch,waited 90min in the queue (my mother is 74) & was finally assisted by the branch manager,who promised to transfer my father's account (no ***) to my mom's name & debit details.We paid R365.60 via EFT on 28/8/2015 to my father's account to settle his bill.The manager called on 28/8 to say the transfer had been effected successfully.However,in Sept we received another acc for R142.50 for my father.I spent another hour in the queue at Menlyn on 9/10,where a mr Herman Botha informed me that we had overpaid,was in fact due a refund, & that we should simply ignore all Telkom sms's & accounts until Telkom manages to 'sort the account out' (the amount is clearly wrong as it shows the same time period as my mom's account - acc no ***, mrs AM Swart - for 29/8 to 3/9 for my dad & 29/8 to 8/9 for my mom).Mr Botha said that we could direct all future communication to him at his email account,but when I tried, I received a return message that his mailbox was full.On 29 Oct we received another sms to state that the account,now R348.33,will now face legal handover. WHEN will this be corrected?
