Poor service by Vodacom HQ staff

I went in an agreement through Elite Mobile with Vodacom to have my selfoon contracts changed to a Smart S option with a reduced Sub + 1GB data free. After a total mess up by Vodacom my package was changed to a Smart S + and the SR1- ********** ********** was closed. The local Vodacom Staff in Vredenburg tried their best to explain to Vodacom staff by phone and email about the agreement between me and Elite Mobile, however it seem to me that the staff at Vodacom HQ do not have the mental capacity to do their work. In my 20 years with Vodacom I never had this poor service.
