Over billed and cancellation never processed

I joined get more at the beginning of the year with high hopes at a charge of R57-00. After a few months they phoned me to upgrade my service and I agreed to an amount of R129-00 for Getmore Plus. I cancelled the service in June this year and they told me that my last debit order will be at the end of August. After I received a notification from the bank that they deducted money at the end of September again I phoned to find out why and apparently somebody tried to contact me to confirm the cancellation(This never happened). This after I sent an email to cancel the service. After this I delved deeper and found out that they have been charging me for the normal Getmore 247 on my Cell C account and for the Getmore plus which they deducted from my bank account. From my experience the service is poor and does not live up to the hype. Please be cautious when signing up.
