No-joy

I keep getting threatening emails from a Siphiwe Langa - Teljoy. The more I respond, the more vague and threatening responses I receive from Siphiwe Langa. Is there no one at Teljoy that monitors Siphiwe Lanaga's work?

I am in the final month of my contract and I agreed to pay a lump sum at the beginning of December, in writing from Teljoy, but Siphiwe Langa thinks it a good idea to send threatening emails without fact-checking or even seeing previous emails.

Totally unprofessional and irresponsible.
