Disgusting & unprofessional service

For the past 3 weeks, Vodacom has been unable to port my number back, onto their system from FNBconnect. The Branch Deputy Manageress took responsibility for the problem & regularly promises to deal with the issue & contact me. My account is approved, which isn't the problem. She keeps alleging that Vodacom's porting department hasn't ported my number in despite numerous emails, SMS's & promising to do so. As that staff doesn't work over weekends, I'm now going into my 4th week without a solution. Does Vodacom want business, or not???
