Slow response by Vumatel to give service support

My account was suspended due to my Card details not being updated. However, I paid my account and I was promised to be reconnected in 24 to 48 hours and now I sitting on 6 days without my internet connection.... My kids school work due dates have come and gone and we are told we will be connected... When we complain we are sent to a robot that select choices that lead one to nowhere.
