Account paid in full but no response nor paid up letter send. POOR SERVICE

I have paid my outstanding on my NPC account in full on the 08 May 2025. I have forwarded an email to SYMINGTON & DE KOK. Till to date I have not receive any paid-up letter on this matter nor did I even receive an email stating that they received the payment.

This is utterly poor service which you receive.

If you do not provide me with a paid up letter before the end of business today, 12 May 2025 I will be forced to take further steps and also put an article in all the mayor newspaper in order for everyone to read about the poor service delivery you received. But the thing you can do best, is to threat a customer. How do you understand that?
