Vodacom a bunch of ********

I had a small R171.01 data bundle with vodacom for the past 9 years.I haven't made use of it for 7 years. Yet every month they have been debiting me. I wasn't too concerned but then in November 2021 i went to vodacom to cancel it once and for all. The lady even laughed and said she couldn't believe it was so old and we weren't even using it for the last 6 years (she could see on her system) She gave us a number to call (***) I called the number (even sent vodacom proof as i callef from my laptop and calls are stored) spoke to Shaheed on 30/11/2021 at 10:36am for 10 min and 29sec who confirmed it had been CANCELLED. Then all of a sudden in January 2022 they started debiting me again????? I reversed the debit order (as it had been cancelled for 2 months) NOW all of a sudden i have been handed over to MBD and numerous attorneys who keep calling and telling me to pay my vodacom account! This is ridiculous and i want it sorted out ASAP. I even sent an email to vodacom customer care and NOBODY has responded. And MBD are calling me 5-8 times a day! Acc I***
