Unauthorised upgrade

I just walked in at Vodacom Clearwater to do an upgrade for a new phone since I'm long overdue. To my surprise when I get there I'm told I've already upgraded. Not only is this shocking but it is very disappointing. 1. Who signed off the upgrade without my knowledge? 2. Where was the phone delivered? <br> <br> <br> If it was a telephonic conversation surely there should be recordings? And if it was a face to face conversation, how would a person using an Identity copy that's not theirs be allowed to make purchases? <br> <br> What happened to protecting your clients information? <br> <br> May I be contacted before close off business today. F on my prepaid mobile number. ailure to do so I will lodge a formal complaint to the Ombudsman. <br> <br> Regards<br> Lebogang
