Unacceptable Behaviour from Call Centre Operator

So I received a call on Wednesday around 4:10pm about increasing my data plan. At first the offer sounded good so I continued the call, when I was about to accept the offer I asked the lady so how much will my bill now be she answers around R900 and some change so I said oh no that is too much for me right now as my husband is currently unemployed. She was so rude and just hung up on me when I said I cannot afford it like I wasted her time on the call. Very, very disrespectful of the situation we are currently facing.
