Harassment and Damaging My Name

I am tired of being harassed! A mail was sent, I posted on Face Book and even left a message on your website contact form. How can you call yourself a business? Communicate with your client Planet Fitness that decided even after cancelling in 2012 and payment was made that you must start harass me more than 2 years later for outstanding payment of over R25000. Not receiving any statements but just demanding money. I am fed up with SAYA you keep on harassing me and damaging my name by threats even after all communication and facts was sent. I don't get any answers on questions like what type of company will demand more than 2 years later payments? I gave you 24 hours from yesterday and time is ticking it is almost up. I will take you legally further for harassment and damaging my name as you and your client Planet Fitness pleases. Sort this out!!! Don't call me I want written proof that you take my messages seriously!!!
