Vodacom Business - your call center doesn't have a clue!

Today I tried to call Vodacom Business to find out how to go about cancelling some contracts with them. Start off with the number on the statement ***, they say I must phone ***, hold on go through the 101 steps to reach someone to talk to only to be told to phone ***, again same process, only to be told to phone *** and then get told no I must phone ***.... It is absolutely ridiculous to be pushed from pillar to post and still no answer. I want to cancel my business account with you, the lines have expired so what is required in order for me to do this? And where do I send my request? SO FRUSTRATING!!!!
