Slow to respond when one does right

I paid my credit card off on the 15th of December 2022 and I’ve doing follow ups on a weekly basis to get my paid up letter but no one seems to care. They are quick to send us sms,calls and emails when missing payments but they are slow to send us simple paid up letter. They’ve been sending me from pillar to post whenever I call to request my letter. Please can I get my paid up later today and update my credit score as quick as you update it when one doesn’t pay on time
