For over 3 months I've been trying to cancel a Vodacom contract that ended in 2015

<p>My contract ended in 2015 and I've been trying to close the account for over 3 months. During October 2016, I had to speak to three retention call centre agents before I was assisted, when I finally thought my account was closed, Vodacom continued debiting my account. I tried again on the 29th of November 2016 but could not get through. I finally got hold of a retention agent on the 4th of January 2017 and she assured me that my account is closed and I will be reimbursed retrospectively. On the 25th of January 2017 my account was debited again.</p> <p> </p>
