no response

Last week thursday I got a call from Romeo at vodacom stating he will call me back as I never answered. I responded to his email yesterday and asked top be contacted. The reply came from someone else stating it will be escalated and will be contacted within 24 hours. I want to upgrade my contracts. I dont mind going into the store but I will refuse to pay the R150 upgrade fee as i upgrade a week ago online and have not received communication.
