Poor service

Agreed to an upgrade on my current cell number with Mondo MTN and was recieved. When I contacted the call center the team leader Aiden Fischer that it was a mistake from the consultant and won't be receiving the upgrade. This was although the consultant informed me it would be on my same number and I would recieved my current benefits and more data to which was agreed, approved and accepted. I was never informed of a new activation. All that I was told that the consultant will be addressed. But what about the customer who was promised delivery! Poor service Mondo and Mtn
