Faircape issue LETTER OF DEMANDS while normal people send emails

Firstly, I just received an INVOICE for some letter of demand. When I query the invoice, 4 weeks later I get told that it was for a LETTER OF DEMAND (that up to date, I have not received). Secondly, without asking me for proof of payment, re sending me the invoice - in other words .... NO COMMUNICATION, they just issue a LETTER OF DEMAND Thirdly, they add the amount to my statement - WITHOUT even responding to my query (for 4 weeks). So they expect me to pay the account, but up to date have not received anything (NO LEGAL CORRESPONDENCE). My question? * Do they just send invoices to their customers that PAY their salaries every month to try and get more money? Because I did not receive any LEGAL LETTER. * How much money do they collect monthly by doing this. Oh - you are late: LETS ISSUE A LETTER OF DEMAND FEE. * Surely they are *********** if they take 4 weeks just to respond to 1 email??? But there is time to ISSUE LETTER OF DEMAND INVOICES? * Lets have a look at consumer act - WITHOUT NO CORRESPONDENCE, they just issue LETTER OF DEMAND.... ?? NO correspondence! Their first correspondence is a letter of demand? * Do they know what they do? I truly think this company should be investigated and all Body Corporate's should be aware of their MODUS OPERANDI... Unless the Body Corporate's are also involved in this.
