PAID UP LETTER

I had an account with RCS which I paid up in 2014. I requested the paid up letter 48 hours ago and still have not received it . I called again yesterday to follow up and Natalie told me Nolubabalo is off but my request was forwarded to the relavant department and I would get my letter on time . I still haven't received the letter and I am tired of calling. The service is very poor, call center agents are very ***********. I need the letter today, can someone who is competent please email me the letter.
