Services not working

Hi I need urgent help. I upgraded 1 of my accounts at vodacom last week. Since then everything went wrong. My one contract can make calls but not received. I phoned customer care and numerous people tried to help me, each time they tell my they will phone me back, i cannot receive calls only make them. My data router all of a sudden connects but doing nothing. I spend average R1500 on contracts per month. This is my work phone and with router i am doing reports and e-mails i cannot go without it. The response i got is that the issue have beem escalated, it will take 5 -7 working days. I cannot afford being offline and unreachable for 5-7 working days. I need urgent assistance and the issues resolved as quick as possible.
