Unhappy with false advertising

This Telkom outlet @ Clearwater Mall has old adverts at the entrance.... I got to the store on Sunday 12 July 2020 looking for the exact same router that’s advertised on the entrance... I was told by 2 of the assistants that “those are old prices” when I asked why is it not removed as it is deceiving.... the one guy employee told me that every customer complains about it but nothing is ever done about it. My request is that, please have it removed from their entrance as it is deceiving to customers. There is an advert for a D-link LTE router with a cash price of R1299 but upon request I’m told it’s now R1600.
