The Worst Service from agents

I had the worst experience today. I have been struggling to activate the new app on my phone. It prompted me to go to an MTN store for identity verification. I went to the store and the consultant said they are not trained for my enquiry and suggested that I call customer care so they can advise her on what to do. The agent who answered the phone was rude, she said she doesn't know how to assist. There was a back and forth between the 2 agents and no one could come with a solution as I was instore. I left without assistance and this is the second agent who was rude to me on the phone today.
