Data contract

Curse will be the day you’ll sign up for Vodacom data contract.i had a Vodacom data contract with them which was for two years of which it was supposed to have ended end of April this year , I called them in the middle of April to ask them to cancel it they said I called late I should have called 30 days before meaning they won’t be able to cancel it but they were going to process the cancellation for May , meaning the last debit was gonna be end of may which I understood , tell me why they debited my money today ? I remember they kept on telling me that I’ve been a loyal customer and they were offering cheap data than what I was paying before and I told them that I wasn’t interested and confirmed that I wanted to cancel , even made a follow up . I’m so hurt because their data is even way expensive , I just want my money back . I don’t want discounted data nor cheap data I want them to cancel this thing and send my money back , these people are ruining our credit score!!!!!
