Covid 19 Cash flow relieve fund

i requested to close the Covid 19 cash relief account, i have done a direct transfer of the settlement amount directly to the loan account, FNB keeps sending me emails to send proof of payment, i cannot send proof of payment cause you can not get that if you are transfering from 1 of your fnb accounts to the loan account(inter account transfer), FNB has access to my Easy account and can see clearly that the settlement has been paid to the loan account, but they still refuse to close the loan account, please note i will not be paying anymore fees or interest due to delays caused as the account its still not closed, can someone please, please give me a call and close this Covid 19 account.
