Worst Customer Experience

I recently paid up my MTN account. Thereafter I requested for a paid-up letter from the department. I have been calling since yesterday and today is 6 day's after the payment was sent through. This is the worst customer experience I have received. I have called 7 times already no one seems to be assisted me. The last person I spoke to was Kgomotso which said the letter will be sent within 24hrs maximum. Till now it has not been sent. Mzwakhe Mkhwa**** assured me he will call back and check with with Kgomotso yet till now no email was sent to me. I requested to speak to a manager I was put on hold till I dropped. I feel for other customer's accounts which are being handled by this Company. Your agent's do not care about customer experience.
