Pathetic and lazy, MTN couldnt care less

My data bill has more than doubled in the last 30 days. My 7 Feb invoice is suspiciously high. I want to investigate, so I load itemised billing on my account via MTN active (2 weeks ago), but cant view it. I call 808. Person says it was emailed to me (I double check my email address), but of course, nothing is emailed to me (not in my inbox, or spam folder) but I get charged for it! Again I call 808. Person says I need to query data bills via data validation. I do this. I get a reply that all charges are correct as per \out of bundle\" rates and usage. I then ask for a breakdown of my data bundle purchases for the month, but data validation sends me back to 808 CS. Person at 808 CS says that I need to query with data validation?! Back and forth we go. Nobody interested in doing their jobs, or making the effort INVESTIGATE. Smug reply from faceless, nameless person (no accountability if you don't know my name and cant see my face?) telling me to go to the ombudsam? Cant even reach (or TALK to a human being) in retentions directly anymore. Yes, I do want to cancel my out of contract number on this basis. All you get from MTN is reference numbers. My average spend p/m is over R2000! "
