HARRASSMENT & ******** - Computech Credit Services Pty Ltd

HARRASSMENT & ******** - Computech Credit Services Pty Ltd What an absolute nightmare, its now a new year and these people are still harrassing me on my work email and continous smses with an amount that seems to be going up each month. Yet when i called them they failed to tell me what service i owe them for and when i demanded the manager, they dropped my call but yet the whole of 2019 they have been sending these horrible communications and threats of my name being blacklisted, somehow even when i block them, they still get through!!!...where can i go for proper assistance and for them to stop all contact?
