Telkom, fix this or I'm going to court

I have had it with the *******! You have been overcharging us almost monthly and now after debiting us correctly, you still want more!

If Telkom does not contact us in 24 hours, I will be taking this to court as I am sick and tired of being overcharged. Either you refund what you owe, or you do it in court.

I am done with being ****** by Telkom for something that is supposed to cost R569.00 and I'm paying over R1000 almost every single month! This is not what businesses are supposed to do. I am disgusted by the service we are receiving and every time we call the agent just says "I don't know what to tell you, your account is in arrears."

I am through with this!
