False Advertising.

Good Day. I have a huge complaint against Homechoice and need urgent assistance with this matter. In June 2020 i bought a heater from Homechoice, i did my order online, the online page/site stated as a first time customer I was going to receive a R200 discount on my first purchase right, wonderful news to me so i get excited and make my first online order for a heater which was R500, i made my first initial payment of R300 in July 2020 assuming that would be an upfront and once off payment. To my calculations and the online "R200 discount" given, i believed the balance of the account would be R300 which is why i paid that amount. NOW here is the problem. Since August 2020, on a daily basis i have been receiving harassing phone calls from Homechoice agents demanding payment of the outstanding balance for the full amount of the heater. Ever since i have been harassed by these very rude, very blunt call centre agents and according to them have been handed over to their attorneys. After trying to ask for assistance in simply trying to figure out why they would falsely advertise these discounts, basically trapping customers in debt, i get billed arrears on this account every month. Ive contacted head office, the complaints office, every department within Homechoice to try and get some clarity on this account. I dont have a problem paying them what is owed on the heater, however, had this problem been addressed and attended to with my first complaint, it would not have accumulated to this high fee they are expecting me to pay now... It has now become a huge problem for me as i am now feeling harassed and feels as if they are trying to ****** money form me... Please, i ask for assistance on this problem as Homechoice head office nor complaints management department has offered me zero help.
