Telkom and Nudebt with endless messages that I owe them.

I would like to get help from someone to sue Nudebt and Telkom for the harassment they are putting me through. I have been receiving messages from these 2 companies claiming that I owe Telkom. I've been to the Telkom branches a few times but nobody can explain why they say I owe them, now Nudebt has joined in. I have never received any call from both of them all I see is messages telling me that I should pay. I really need someone to help me put an end to this and sue these people, surely they have extra money to make me rich.
