Mtn complaints service a joke. No feedback. NO HELP FOR SPAM VAS

I contacted mtn call centre and complaints centre about two weeks ago. It is ridiculous that a big company like mtn had no way of blocking your phone permanently from the VAS services. So every day we as paying users have to dial in to check what we ate subscribed to and delete it ourselves. Who knows what money had already been taken off by these people. Without your permission. Because of you do NOT reply no to their bogus SMS they just automatically subscribe you. Is this legal??? I think not. Still no feedback from mtn useless services. No protection for their clients. Vodacom and cell c you just need to send an SMS once to block ALL vas services permanently. This is *****. Every day it's4 or 5 different VAS sms's. PATHETIC MTN. GET WITH THE PROGRAM. mtn users do yourselves a favor. Dial *141*5#. Check what VAS (content services) services you are paying and the reason your airtime is disappearing. It's time we all stood together to stop this theft.
