BREACH OF AGREEMENT

On the 3rd of April 2019 I logged onto MTN"s online website for an upgrade and created my own deal. I selected the package "MTN Made For Me Small" for R99 and a 2gig booster for R169. I then chose Samsung S10 64gig as the device for R331 and it indicated that this would come with free bluetooth speaker and earphones. I then chose my device: "Total Monthly cost for 24 months R599". I received an sms saying that the upgrade was approved. I will be receiving my phone tomorrow. However i was shocked that my billing reflected that the current unbilled amount is currently R910 and I have noted a promo charge of R566 in addition to the R99 and R169. This is not what i signed up for. The agreement stated R599. I signed up for R599 in total. This is totally unacceptable. Please go and check your records and contact me urgently. I have no qualms about taking this to the media should this matter not be resolved favourably. I have noted that others are having similar issues.
