DSTV is desperate and *****s money from their dormant clients!

DSTV thinks they have the right to add banking details back to a profile and take a debit order. I removed my banking details from my profile more than a year ago, and today I get an sms thanking me for my payment and advising that my account has been reconnected. I have not accessed the app, and I have deleted the app from my phone. Who gives you the right to just reactive it again. My decoder is not even connected!
