Upgrade offer Friday LG G6 with TV Monitor - nowhere in the Upgrade process you get warned that you are not eligible for the free TV due to numbers already reached. I have upgraded my Contract with Vodacom - being a long standing customer with them and always paying my account without missing a payment - but on Friday I have upgraded my contract to the LG G6 with the Free TV monitor offer - at no stage in the whole process or even when I received confirmation etc did I get notified that I do no fall in this number of available TV's. I feel that is not being upfront - because I might have reconsider my option to Upgrade if I knew that I am not eligible for the TV Monitor. I received my phone today without the Monitor and only then realized that I might have not be eligible. I feel really being cheated on this matter.
