Poor Service

I had a 2 year contract with Vodacom which was due to end in September 2018. I called and cancelled this contract in April 2018 of which i have the ref number and name of person i spoke to. I was told that the last deduction was to be in September 2018. End of October i get a deduction of R360 which was not even my contract amount. I called vodacom and was advised that this would be escalated and feedback would be given to me in a week. Its gone 2 weeks now and i have not received any feedback.

What pathetic service is this to someone who has never skipped a single payment??

How do you deduct from someone's account with no explanation???
