Unprofessional caller for vodacom promotions.

Vodacom was phoning me about a promotion. I told the lady on the phone that I would come in store to sign rather than accepting the offer telepathically. I was still asking questions about the product but because I didn't accept it telepathically she just said "thank you" and put the phone down in my ear. Because of this I will RENEW my data contract with CELL C at a higher price, rather than entering another contract with Vodacom. She was so rude and unprofessional.
