Sceptical

So I write a review about FNB not keeping their clients credit scores up to date. They reply and give me a reference number and everything, the lady calls me and assures me that the account will be closed and my status will be updated. Well we at the last Friday of the month my account still reflects, nothing has been closed and the loan still shows on my credit status. Now I know you said by Friday and I am writing this as the day begins,but forgive me for not trusting banks so easily. The last time I squared up a loan at FNB, I didn't get a paid up letter and I doubthat they even checked if I over paid. Why do I say this because they deducted and I made out a debit order myself so that I don't skip a payment. I made 1 payment to many on that loan,I am sure of it. But hey they will say I am wrong
