Mondo vs Vodacom

I did not want to give Mondo any star, they do not deserve it! I had a lady call from Mondo, (who are apparently a third party to Vodacom & MTN), her name is Carmel, Employee Ref No: 9723, she said because I am a loyal customer of Vodacom and because they must reduce their rates my Vodacom package will go from R650 to R499 and I will get a router!! This morning 09/4 I received a quotation for a router @ R499, for 24 month, that means she blatantly **** to me, I even told her I have a child at home who is unemployed and that I cannot afford anything additional. I've now been trying to put in a complaint at Vodacom, what a mission, there is just nowhere you can put in a complaint with a human being. So what I would like to know from Vodacom is, how do you allow a third party to use your name and deceive your customers, it's shocking!!!!!! Mondo, you should be ashamed, trying to con and manipulate people into purchasing unnecessary items in this day and age when we are all battling to stay afloat!
