Loyal for almost 20 years just to be disappointed

Have been with vodacom since 2001, been loyal and always paid on time. Eventually grew my business and had red carpet profile with vodacom with multiple contracts etc. My main number contract expires end of April so I went to get an upgrade for the Samsung s10 plus with unlimited calls, and the guy at the store quoted me +/- R 2500.00, went to cell c, and exactly same specs their quote was for roughly R 1500.00. So I went back to the vodacom store, and told the guy about the cell c offer and wanted an explanation, and he simply said "Then you know where you can buy it" ... as a loyal customer for almost 20 years, seriously considering porting to cell c, because this just indicates how this is truly just a system and they dont care about loyalty.
