No stock online or instore available for specials

HiFi Corp ran a special from 05-16 April 2023 on the Milex Dual Air Fryer at R1 999.00 On the 6th I phoned the stores around me to check stock and was told that the stock had not yet arrived and that I can also order it online and if not successful then to call back the following week. I created an account online and added it to my shopping cart order and it indicates the price of R1 999.00. I then clicked on the Secure Checkout and it showed that there is no stock for delivery or collection at any store. It did however allow me to go to the next screen but then it changes the amount to the original amount of R3 499.00 I have phoned the HQ on ***numerous times but the phone just rings. I have also emailed them and they actually responded to the first 3 emails and in my last reply, I asked that a manager please contact me. This did not happen. I spoke to the N1 City branch again on 14 and 17 April and they informed me that they had still not received any stock. I have checked the online store now and phoned N1 City and they indicated that they have not yet received any stock. This is clearly false advertising as no stock was available countrywide. I expect HiFi Corp to honour the advertised price of R1999.00 This is not the first time that they advertise items and then do not carry any stock.
