FNB has not paid over credit balance to estate account after executor requests - this is ongoing for 3 months!

Good day,

A relative of mine died 1 July and we advised FNB of this. There was a credit balance of in excess of R14000 on her account. The executor has contacted you to transfer this money to the estate account and you just do not react! It is now 3 months since she died and we want the L and D Account finalised but this money does not refelct. This is NOT your money! Who do I need to contact to have this transferred to the estate account as I think waiting 3 months is now long enough!
