Device delivery

I recently upgraded my contract 5 August 2026 and I was supposed to receive a new device with the contract. The delivery was done two days later however my fingerprint was not verified and the device was sent back. I followed up on this twice and was told a new delivery would be scheduled but to date I have heard nothing from MTN's besides a Whatsapp chat based app to schedule delivery with no feedback thereafter. It's already past the 10 days timeline that they mentioned that I would receive the item. Very unhappy customer that I constantly have to be following up.
