shocking service

my contract term was ending in July, i spoke to a consultant Randall Cairncross on Wednesday through the chat service, i have a copy of the conversation. this is my business line and the line is connected to my online banking also. i was very surprised when people start emailing me upset telling me i am unavailable on my cell phone! i find out that my number does not exist anymore. i could not call vodacom i could not access my banking because of this. i went from the chat service to 082111 call centre who transferred my line to some zulu man's phone, to 082114 call center and eventually got help on *** who told me my line would be unavailable for the whole of today as it converts from contract to pre paid. i have the entire conversation with randall on mail and this conversion process was never mentioned to me so i can make provisions for not having a line for today. i am currently in the market for a new contract and have been with vodacom for over 15 years but i am thoroughly disappointed in this service
