Deals deals but not meant for me?!

I am so disappeared in MTN, its 2am and cannot even by the injustice.. I app**** for a contract with iphone 12mini at R500 and something. Sales person called, got approved and now it's closed to R800 after asking for the cheaper one. Still agreed to continue. Well declined to take a second contract.

Got home to tell my partner the great deal I got to recommend her to get the same. What a shame on my side. As I am someone with medical conditions she wanted me to get the iWatch also. Went online for the same price I can get an iphone 12mini and an SE watch but because MTN agents are just in to ripping people off. That was not even offered to me.

Should I cancel the contract once or should is MTN gonna help me like they were suppose to in the 1st place?
