Mondo sales staff lying to customers to make sales!

Lying bunch of sales consultants! My husband who is a Vodacom user, gets a call telling him he has been 'preselected' for a MTN Mega deal. Speaks to a girl named Varsha who told him the deal is 30gigs for R149 p/m..confirms this with me as well but when her manager or whoever, named Michelle confirms with m,y husband, she says its R298 becasue he qualified or 2 deals. he told her he only agreed to one but they put him down for 2 sims. He tried the online live chat with Varsha who came on and just says ' the above is correct' and went off and has not called back! We called to cancel and some one in teh cancellations dept confirmed that he was put down for a debit of R298 p/m for 2 sims. I hate ***** call centre ******* like this! Makes me never want to ever give another telesales person the time of day again. We rejected the delivery of the sim cards but were kept on hold when trying to call the cancellations dept.
