False advertise and poor communication

Hi was at 4 outlets including the MTN direct online and they were unable to assist for the past 19 days. many poor excuses, that its not their task, or job. so say. (is this were MTN is heading to, having second thoughts of take on a contract with them) Anyway would like support as to why you advertise and don't have the product code available for all the service providers, your stores and franchises to sell the product. many poor excuses from all your call centers and what's worse in no manager are available to address the issue. so i am looking for the Samsung Galaxy A51, Blue for R369 and the Samsung Galaxy Active watch for R49, for a total sum of R418 on a 24 month contract, the system however on all 4 store and online shows R449 for 24, which is incorrect, offer is on Page 19 of December 2020 magazine issue. why is no one in you company capable of making a decision ( online to the various number 083123 ***, also you store franchises manager are also very unhelp and some blunt, (Secunda Mall), one in Menlyn Park Mall just said the managers out and can't help you, all tried to get a deal code and no one could find it, if the computer did not say anything they were stuck. I see this as false advertising and poor communication for a company that sells communication. How sad.
