Telkom is the worst

For as long as i can remember Telkom has given me terrible service. All im wanting is a paid up letter of my account. I've requested this for nearly a week now and all i get is that the call has been escalated. i kept saying this is urgent but they do not care. Please send me my paid up letter this week still. They dont reply via email or facebook and calling to them is a waste of time, never will i sign up with telkom ever again
