Capitec Bad Bad service

Called the contact center requesting a paid up letter since my account was settled in december 2017 and Capitec still listed me on ITC. I was told to send an email and will get the letter in 3 working days. The email was on tuesday the 15/01/19. Called again to check if i i w ill receive the letter and was told they count the 3 working days the day after the email was sent. Their service sucks the agent are rude and unprofessional> one of them asked me if I wanted to speak Sotho cause she assumed i cant understand english. Bad Bad service. All i want is a paid up letter so i can sent it the buereu
