Upgrade problem

Poor service regarding upgrade of my contract, below what happened and did not happen fom MTN side 04.06.2020: I was at MTN Mall@Reds to do an upgrade on my data contract I was supposed to be upgraded to the My MTNChoice 30GB contract with the promotion code *** CT 01352 DG which entitles me to 130 GB Anytime and 130 GB Night Express data 18.06.2020: I went to the store to find out why I am not receiving my data as per my upgraded contract, I was informed that the wrong code/s was locked for the upgrade and a ticket was logged to get it rectified. 25.06.2020: I phoned the store to find out what is the status on the query as it is not resolved yet and was informed that the ticket was closed by MTN and it will be re-opened 30.06.2020: I phoned MTN Mall@Reds again and was informed that they can see that it is in progress and will escalate to one of the supervisors at MTN 03.07.2020: I phoned the store again and was told that they cannot help me any further and that I must take it up with MTN myself I then phoned MTN customer care and after spending 45 minutes on the phone I was informed that MTN Mall@Reds will sort this out and give me an update 06.07.2020: Email sent to Mall@Reds MTN to follow-up 10.07.2020: Follow-up email to MTN Mall@Reds 14.07.2020: Follow-up email to MTN Mall@Reds Received email from them requesting that I sent them the original upgrade offer email I have received, I then forwarded the email to them 15.07.2020: Follow-up email to MTN Mall@Reds 16.07.2020: Received email from MTN Mall@Reds stating that the query is resolved, I then rep**** that I do not agree as nothing was done to resolve it I then received a call from Mall@ Reds and was informed I must reply on the mail with the original offer to MTN and they will sort it out Email was then sent to *** 17.07.2020: Follow-up email sent to *** 20.07.2020: Email sent to *** 23.07.2020: Email sent to MTN Mall@Reds to request cancellation of the contract as it is still not resolved and no feedback from anyone

24.07.2020: Received an email from MTN Mall@Reds stated that the cancellation was requested, and I will be advised when completed

31.07.2020: Still no feedback

This is now nearly 2 months and a simple thing like an upgrade can’t be done properly, totally unacceptable

I’ve got the names of all the persons I dealt with regarding this
