3 months for an upgrade and still no news or phone.

After several months of phone calls to upgrade my number we finally did so via the online platform. This was in April. We waited a month for the delivery but nothing happened despite having several phone calls during that time for upgrades to which we told the people we already did so. Eventually we call MTN and hear that the person who took our online upgrade approved it but didn't send it through and that we must call the online department. They never picked up. So cool, then lets go in store... did that and they said the guy who took the online order blocked it so no one else can override it. We get told to contact ICASA to complain. Now its been 3 months, Im still without my upgrade yet you hound and harrass for an upgrade.
