MTN support

I requested via e mail a detailed report for excessive data usage for one day, as the app report is insufficient. They asked for verification, which I sent. They asked for further verification which I sent. They send me exactly the same as what I could get off the app. I requested further detail. They ask for verification, which I send. They asked for further verification, which was all on the previous conversations. I send again. It is now 8 days later and I have e mailed them to wake them up. Still no response. So 8 e mails and absolutely no result. My contract is coming up for renewal. Would I chose MTN? That answer is obviously NO!
