Bad ,Worse customer care by vodacom

Vodacom has cancelled the contract I queried but did not refund my money.In their response they dont talk about refund .That's not their concern.

Secondly I have an insurance with vodacom meant for another contract for Iphone 7 which was an upgrade from iPhone 5 .according to them (vodacom insurane)only an iPhone 5 reflect in their books.There is no iPhone 5 in the market now but they are happy to deduct my money to cover for iPhone 5 which ddoes not exist.when I query I m told ,you have to submit proof of upgrade which is in their system.They want me to go and search for those papers failing of which they will happily continue to deduct moiney for iPhone 5 though they know that it doesn't exist.This is total ripp off.I coulnt claim from the insurance due to the fact that on the old insurance it was not changed.
