mtn do not value their customers.

A third party company called Rewards CO **** to me that they calling from MTN Direct.They had all my details which they from mtn ,because mtn approves of them calling their customers for upgrades etc.I declined the delivery of the handset and i called the 3rd party company on 18 November 2018 to cancel the upgrade.They gave me a reference number to say my upgrade is cancelled.It is gone a month and my contact is still locked and i cannot do an upgrade.Reference numbers from Rewards CO- ********** 8 and ********** 8.Reference numbers from mtn- ********** 43 and ********** 37. mtn have burnt their fingers with the Iran scandal and Nigeria scandal and now they in the process of losing me as a customer. My family and I have been loyal mtn customers for the past 20 years.From the days of I-Talk cellular.
