vodacom cancellation horrible service provider

i have called vodacom 1958 cancellation department on the 26 February 2026 regarding cancelling my two line. i spoke to a lady by a name of Noxhebe who said she can decrease the amount that am currenly paying as she will put my two number on a month to month contract that i can cancelled at anytime once i have put a 30day notice .to day i called in the same 1958 to put that notice for 30days to my suprice i was told i was on 24month contact which am not aware of. Am very very angry with vodacom because i did not agree to 24 month contract i said i want month to month not 24 month. Vodacon is the west service provider ever
