Frustrated with lack of communication

I have been receiving messages from this company about owing Telkom. I emailed all the previous correspondence that I sent to Telkom and Petersen Pandaram Attorneys which shows that I cancelled the contract with Telkom giving them 90 days cancellation notice even though it was only supposed to be 30 days. Telkom continued billing me and after 3 x months I refused to pay for internet that I did not have. Nu debt called me and I explained what transpired I even asked them to send me the invoices and was told that I must call Telkom to obtain it. They are collecting debts and sending threatening messages why don’t they have their facts beforehand?

I have tried communicating via email however I have received no response. What is the purpose of sending these messages when you cannot provide evidence to support your claim? Your claims are invalid and your communication skills no existent. Just for your information sending threatening messages does not mean communicating with me.

Go and read your emails and respond thereafter.
