False information given BY VODACOM

hi, I am very disappointed in Vodacom really. I did an upgrade the end of September 2018 via the internet (online) and they advertised that everything is free. no additional fees. even when I spoke to the consultant that called me with regards to my upgrade they told me I wont be charged anything and they will debit the normal amount they normally debit + my additional add sim. which is less than R800 . Now they debited an amount of r1044.91 and when I called them they said that they charged me R150 upgrade fee. And I still need to pay for my handset that I had before the upgrade until that is finish paid even though it was an upgrade on the same number. really frustrated about that. no body told me that I still had to pay that, instead they told my I would start with the new contract amount + the new contract amount. Vodacom advertises false information. and they don't own up to their mistakes. Now they want to transfer me from pillar to post and not take accountability. I will not pay for the last handset and I will not pay the upgrade fee. they have to reverse that and advise client accordingly in future. and secondly they also debit late... I am very frustrated and very angry. seriously. this is not right. how the hell can you as a Vodacom employee give the customer the wrong information and expect the customer to pay. the probably charged me connection fee for the add sim as well. oooh i am so sick and tired of this unfair treatment as a customer. please somebody look into this and rectify please.
