Failure to migrate back to my original contract

MTN offered me a contract upgrade, which I accepted. Later, I realised that it wasn't suiting my needs and I requested that my contract be migrated back to the original one: MTN Extra small. I was told that this could be done but ofcourse you can't connect telephonically to anyone who can help.

On 10 May, I emailed customer care and to this date, I await action. They were very prompt to bill me beginning June for the more expensive contract but no response to the change that I requested. I have numerous references but conveniently the contact centre has no record of them so none seem to work: Reference number: c63afc6c-d431-42eb-9832-60ba54672f2e *** Reference number: 9b71fbc9-b235-4c66-a9c2-61b44e05489c

A very disgruntled MTN customer of over 23 years.
