***** Lies & *****ing at cell c

My contract was completed on the 25th of October with cell c.i always paid over the two year period.All of sudden I started getting notifications on my phone that i have subscribed to various games services etc, which i never did. I phoned cell c to querie it and was told that i "definately" subscribed to these services, in addition my other cell c sim that i leave in my tablet with 100 gigs has also been getting notifications that there are "subscriptions" on it. I have since had to block both numbers. Now cell c keeps debiting me for R200,as soon as i stop the debit order they debit again, this is the thanks i get for my loyalty as a customer, ***** lies and *****ing money out of my account. I paid my contract faithfully, i bought data for R1600 ,i only use cell c and this is the way cell c repays me. If this has happened to me it has happened to others,please dont do business with cell c stay away from them, dont let them get hold of your banking details or you willbe sorry.I will take escalate matters if this not rectified.
