Poor customer service - *********** agents online and stores

It has been months (+2) being sent pillar to post, there has been glitches in the billing system which i have logged and request manual intervention to remediate and avoid inconveniences to me. It appears as though the billing was sorted in November because my account was successfully debited and another 100gig was loaded.

Sadly we couldn't use the data in the MTN SIM *** which was automatically cancelled by system and mistakenly converted from M2M to prepaid. Router SN: 2DN*** shows red light and we cannot access the internet connection. When the SIM is inserted into a mobile phone it also cannot connect to provide data connection.

The MTN customer service is failing to render a service to fix this issue, the MTN telephonic line failed, the MTN store first agent failed at Clearwater, the email customer service box appears to be failing they hate their jobs these people you see by how nonchalant and casually they race through the service. Please see below email thread?

My ask is not unjust or unreasonable it's simply a CPA right that we all have when paying for services from service providers.

I urgently need your assistance to be provided access to the now converted prepaid SIM through the router I received.
