Pathetic service, lack of feedback and communication

After 3 emails sent with the proof of payment, to date we have not received a response nor confirmation that the account is closed, or atleast a status for the very least. The first email was sent on 28 August, another 30th,the 3rd one on 2 September. I want a paid up letter confirming that the account is settled in full. I also want confirmation in writing that you sent a request to all credit bureaus to update my profile as settled. I want this information asap. I gave you 2 weeks now already. My number is *** or *** or ***
