Disgutingly horrible service - Account paid up letter

I am very disgusted by the service I've received from Brooks and Luyt, I've settled my account 3months ago and I still haven't received my paid up letter.

I've called them over 10times, I'm always given number for supervisors and managers that never pick up. Does it really take 3months to get a letter from your admin department? And you managers/supervisors Valery, Linda, Oreo are in meetings 24/7.

Honestly your service is very shocking.... I'm very disturbed by how you handle your business.
