Misleading or false advertising on the Vodacom website

Misleading advertising on the vodacom website or the online sales consutant was unable to assist with a fairly basic upgrade request. On the 20th of Feb i attempted to upgrade my handset contract and add on a Hauwei watch ultimate pro 2 (blue) contract . I submitted a call me back option on the website and was contacted by an consultant who after much debate tells me that in order to get the deal at the advertised price of R489 x 36 months and a prepaid amount of R13869 i need to go into the store. She tells me that she can only offer the watch at R655 x 36 months.This statement make absolutley no sense as the advertisment small print says that this deal is available in store and online (at the adveritised price of R489). All i am requesting is the advertised product at the advertised price. Please see link of the ad as per the online vodacom catalogue. https://vodacom.pubhub.studio/february-26/smart-tech
