Vodacom/Affiliated with Vodacom BAD attitude call

I had a female contact me asking to speak to my partner, I requested which company she is calling from and she advised Vodacom. I told her he is not available on this number, but on the other number as he has 2 contracts with Vodacom. She asked me to give her the number, I asked which number she has. She mentioned a completely different number. I told her that is incorrect, she asked me to give her the number. I told her if she is calling from Vodacom she would have this number. She proceeded to scream at me asking 'how should she know what the number is'

I hung up and could not believe how UTTERLY RUDE she was!
