Bad Customer Service - MTN

I called MTN Customer Svs on the 20th of August to change my bank details on my Account. The agent took all the details and mentioned I would receive a Debicheck Mandate instruction. On the 29th of Aug I called MTN again as I had not received this Mandate and they mentioned no update had been done because my passport had expired and I therefore needed to go into a branch with my passport to enable the update. I went to the Clearwater Branch on the 31st of Aug where I was served by a lady called Rudzani she took my banking details and I also shared my new passport with her to make the updates. I then followed up on email the 6th and 7th of Sept. Rudzani responded on the 7th to say the update had not been updated because my passport had expired. I am totally appalled, why then did I go into the branch on the 31st of August.

My intention in this process has been to update MTN records to ensure that they get they payment and my effort has been met with Imcompetencies in the system. Very disappointed by the service. I don't have time to go to another branch. So if MTN cares they will get hold of me and solve this issue.
