Upgrade to MTN contract has been ignored.
I performed an MTN upgrade on my phone contract, which I have held with MTN for 25 years by paying via a debit order. The upgrade is for a Galaxy S21 phone and an upgrade to my airtime and data contract. This was done on Friday 18 February 2022 but to date I have not had any feedback. When contacting Mondo by phone (ref 1-**********3) I get thrown from pillar to post with no feedback.
