MTN: DEBITING FOR UPGRADES THAT WAS NEVER RECEIVED FROM ANGELIQUE GUMBIE

I HAVE RECEIVED THE ABSOLUTE WORST SERVICE FROM MTN DIRECT. NOT ONLY DID I NEVER RECEIVE MY UPGRADE, DESPITE 28 PHONE CALLS SINCE THE 17TH OF FEBRUAURY, TO THIS DAY I HAVE YET TO RECEIVE A REFUND. MY ACCOUNT IS STILL BEING DEBITED AND I HAVE HAD TO FOLLOW UP WITH THE AGENT: ANGELIQUE GUMBI WHO NEVER RETURNS CUSTOMER CALLS. THIS IS ABSOLUTELY APPALING AND ****************!
