Set back of R600

I am honestly tired of Vodacom holding me back. I have settled the debt of R600 in October, its December now and my record is still not cleared. Just for a mere R600, I cannot purchase a car, house or even get a cellphone contract. Two weeks ago when I spoke to their legal department I was told that my name should be cleared in 7 days.

I've been making this follow up and receive the same response every time I call.

Can someone please assist me.
