POOR AFTER SALES SUPPORT AFTER BEING **** TO ABOUT A HANDSET

I went to a outlet vodacom Wonderboom Junction that is run by Hicell. We went to upgrade to a Samsung S20 + but were strongly advised to rather go for the Samsung S20 FE. We were told that the battery were much stronger (5 ohm) the camera were better too. The manager that were close by confirmed this. We agreed on that bases to go for the Samsung S20 FE. When we received the phone the next day and had a look at i we saw we were **** to. I went back to the store the next day where i put up a big fight about it but the manager refused to correct their lies. I sent a email to vodacom customer care and no response. I phoned all the support numbers but were passed on and no one were prepared to help. There were one consultant that escalated my call but just to be closed tge next day with no resolution. This to me is really unaccessible. Strangely everyone at Vodacom agrees that the lies must me corrected but no help. Now i reported the matter to the obbudsman hopping to find help
