Avoid Alliance at all costs

I paid of my Vodacom account which was handed over to Alliance on the 15th of June. I’m of the knowledge that paid up letters take 7 to 10 working days. I am currently still waiting and they are making up excuses daily. Firstly it was their system crashed etc then it was what what was not logged then now they saying the department that does paid up letters is the issue then it was I only get it after 21 days. I’m not waiting for 21 days because I still need to submit that very letter to credit bureaus. My life is on hold because of them. I wish I was jaded over to a different company. I have never had to wait this long for a paid up letter, it’s pathetic
