********* behavior, pestering call centre agents and upgrading without consent

Hi

I was contacted numerous times by Vodacom call centre agents to renew my contract. I however, wanted to see the phones firsthand before deciding. I visited Vodacom in Canal Walk on Sunday to upgrade and select a phone only to be told that one of the call center agents had already upgraded my contract. When I try and call customer care I was disconnected. I am disgusted by the ********* behaviour of your staff. First, they pested me about an upgrade and then they did the upgrade without my permission. I want this issue addressed and corrected.

Why can't I rate this sort of service as negative stars? 1 star means there is a bit of service
