MTN R249 Deals Issues

Good day,

i recievd a Call from a company incotrated by MTN with regards to my Upgrade that is due, i went to proceed and advcie the Lady that i want the A22 for R249 a month,

We proceeded and handled everything and we ended the call with me unde3stadning that the contract has been upghraded,

30min later i recioevd a call from a diffrent lady advising me the R249 was a missprint in the Yellowtrader and that the actual cost is R259!! What is this!!! I adviced her that they been printing this price since October 2021 on the Samsung Galaxy A22 deal.

Please sort out this mess as I would like to upgrade my contract to this deal with out any hassles... the price was advertised for 3 months!!
