Disappointed MTN Client

I am horrified with my experience with MTN , i have been dealing with them from November 2020 and no date im query has not being resolved. Their Blackfriday deals /upgrades was not managed properly as they had to many different departments and we the consumers suffers for their mis-management.

i upgraded my 2contracts after numerous attempts and i assumed that all was in order, yet to receive a message few days later which i then queried to find out that one of my packages was incorrect, then customer care tranferred me to the Retentions department who then transferred me to the outsourced company who said they will need to listen to the recording , im still awaiting a response few months later.

Only to find out my bill tripled, prorata has been charged twice .Query tickets are logged and we must follow up to be given feedback on what was not queried then another ticket log is to be loaded.

No departments can be contacted directly other than customer care. Its sad that we the consumers suffers the loss and anxiety of dealing with un-resolved issues.

Who can this be directed to, where and how can i get this resolved ?
