Account Settled, No Paid Up Letter

I settled my account that was handed over to you, what is so difficult with sending me a paid up letter and updating my credit profile? You never reply my emails but you can send me many emails thanking me for payment. I called in and I was told the letter would come within 14 days. We just clocked 3 weeks now, and no word and my credit profile is still not updated and no word from you on the paid up letter.
