Unauthorised debits and cancellation of contract is impossible

<p>I only used their services for 1 month and I then cancelled my subscription on the 9th April 2018. They are still trying to debit my account. I reversed the money through my bank and now they have split the invoice amount to two lesser amounts over two months, being July and August at an amount of R349.50 for each of the months. I still have not received a confirmation e-mail from them that this will be cancelled and when I did receive an e-mail from them (asking for money obviously), they advise that I must pay for the additional month even when I did't use their services!</p>
