Lying non existing service!

My contract was about to expire (1 month to be exact), I phoned and I got the amount that I had to pay to settle my account - there after I have requested a paid up letter. I phone everyday to see how far the so called 'escalation' is taking and everyday they tell me I should receive my letter within 24-48hours. Now 2 weeks later, they tell me no I cannot get my paid up letter, because I need to wait until I get my last statement so that it can reflect the amount. Why did I make the effort of settling my account early if I can't even get a paid up letter. Why didn't they tell me this from the beginning?! Why did they LIE?!This is pathetic! I am going to change from Networks, because Cell C are amatures.
