Forced to Upgrade My Package by a rude consultant!

I just got a call from Vodacom and the consultant tried to upgrade my plan from my current one to a higher plan. Little did she know I was migrated January of this year. After trying to justifying her case, I was adamant that I do not want to move to a new plan, then she literally hung up while I was still talking.

It's clear that these consultant get a commission for every person they get to "move up" to a new package. It explains why she spent forever trying to convince me but got so irritated with my decline that she hung up on me when I said no. Service like this frustrates me. I wish I had her direct number to let her know that what she's doing is wrong - as much as she's trying to make her commission, clients aren't obligated to "buy" whatever she's "selling" and she needs to be okay with that and treat them with the very same respect and enthusiasm as when she initially called.
