discouraged and false advertising

so i went to vodacom and app**** for a new phone iphone 12 pro max, everything went well and the price was R949 /pm, then when it came to odering the phone, the guy assisting me was told and discouraged that the phone is not available. I opted to wait but the other consultants discouraged both me and the consultant assisting me, telling me the phone hasn't been available for a while. I had no choice but to take the option i never wanted which is iphone 12 on the 12th February which initially it was R797 on the pamphlet but to my suprise my installment is now R789, and then now on the 20th i was told the phone is now available. im soo disappointed, i haven't had the phone for even a month and l aready i dont like it.
