Vodacom Galleria BIIIIG NOOO NOOO

Have you ever had to BEG someone to take a debit order? To take your money? Well, WELCOME TO VODACOM!!! You ask (BEG AND PLEAD) them to debit your account on the last day of the month, they take it off either the 25th or the 5th. I had to go in ATLEAST 15/24 months to pay cash. I cancelled BOTH my contracts on ONE email. They cancel 1 and never the other. I phoned them after my email, after last payment and CONFIRMED BOTH were cancelled. Well, they only cancelled one. They tried to debit my account again December - it didn't go through. I phone them January to ask what's happening, they tell me I have an outstanding amout of R460 for "airtime" that was already allocated to my sim (mind you, I never ever used those simcards but whatever) I agree to pay. They never took the debit order. I sent email after email (Feb & March) hoping to get a response from someone. TRUST ME PHONING DOESN'T HELP! Eventually someone phones me in April telling me now I owe then R1580???? They cannot give me answers. The want proof of the email I sent them? I sent BOTH on ONE email, I phoned, I CONFIRMED. Unfortunately I changed jobs 01/07 2019 so I don't have access to that email and now I'm paying for it. For something I've never used. Total incompetence. If you ever want to cancel your contract, remember to take crayons with!
