Appalling Service received for a so-called "Beneficial Migration" of my cellphone contract.

I just received a call from the Vodacom Migrations Department for what was referred to as a beneficial migration of my cellphone contract and I have never been addressed and spoken to so unprofessionally before. Absolutely appalled by the so called service department and seriously considering cancelling my contract ASAP. I have been a long standing customer and am highly unimpressed!!!
