Unsatisfied customer

On the 29-06-2025 I decided to upgrade one of my lines online for 50G of data for R199 I even received the contract application (attached) confirming this but my surprise this is not the deal loaded on my line. I have made numerous calls to MTN to try and resolve this but I was sent from pillar to post without any resolution. I even resolted to cancellation of the contract but still that is a hassle, even today I tried calling but received no assistance just stories. I have been a loyal customer of MTN for a long time and I deserve better.I can even send you call reference numbers if needed. Kindly assist with this matter.
