When will MTN care about its customers

I've been an mtn customer for longer than I can remember. Unfortunately, over the years, their rates escalated, their service has deteriorated to sheer incompetence and inefficiency and their greed has led them to robbing many a unsuspecting subscriber.

I app**** for an upgrade to my contracts in November 2020. After numerous calls and wasting hours of my life holding on for their call centres, I was told they have no record of my upgrades and I need to reapply. I reapp**** with the call centre and again after numerous calls and spending hours on the phone, I was told the upgrade has been approved but to date my contract has not been updated. MTN, due to their inefficiency and pathetic service is now charging me the exorbitant out of bundle rate.

I have visited the MTN store, sent them an email, sent them messages on social media but no response has been forthcoming.
