Vodacom are ***** and ******

I'm very angry and annoyed with vodacom that mislead and dupe people into taking contracts. Last week I received a call from Mr Sibisi from Durban who is working for vodacom rewards department. He told me that vodacom will like to reward me with a laptop contract at a lesser price. I told him what type of a computer I want and he said to me the computer he is giving me is worth R20000, has 8gb ram, 500gb memory and its very cool, he was so forceful that I get the contract because I will miss out and I eventually agreed because I need a laptop. Today I received the laptop and it's not what I sign up for, these vodacom consultants are ***** and are giving vodacom a bad name. I'm taking this thing back and I'm cancelling the contract, I didn't even open the box of the computer, because the sticker on the box show what type of a computer. The computer has 4gb ram, 128 gb memory and it doesn't even worth half of the price he said it's worth. What I can say is that please don't ever conclude a contract with vodacom consultants, they are *****.
