Superflex Data Not Loaded

I subscribed to superflex on the 25 of October and my subscription was supposed to renew on the 25 of November, so accordingly MTN took the subscription amount from my account and only renewed the minutes and sms, but they didn’t load data on my account, I’ve been calling MTN every other day to sort this without any joy, according to MTN customer care, superflex team said my account wasn’t paid, after which I sent my bank statement through, but it’s been 2 weeks and nothing has happened no feedback whatsoever and there’s no way of reaching the superflex team directly.
