Pathetic service Vodacom

I upgraded my contract in March to a S22 Ultra, the phone came with free screen replacement, a watch and buds. 6 months later the phone screen cracked while on a Samsung wireless charger. I contacted Vodacom and they don't want to acknowledge the free screen replacement that was part of the launch promotion. The consultant went so far as to say that the phone does not come with a warranty. Samsung holds vodacom responsible and expect me to pay R7000 for a new screen. Becareful when taking up specials, they will promise everything to sign up the contract and when it's time to deliver they cant.
