UNBELIEVABLE!!!! I HATE TELKOM

So in May i took out a contract online and struggling with sooooo many which i will not bring up now as i brought them up on my last complaint to Telkom for which i still have not been called back about. but ya that's telkom for you... anyway now i get an sms telling how much will go off my account at the end of the month and it's way more that i am aware of. apparently i was charged for courier of the device and sim and connection, both of these charges were never mentioned to me when i took this contract. to top it all off, i was debited 499 during my application as that is what they do to confirm banking details and now i want to know WHERE is that money because the agent told me it would be credited into my account????? Can Telkom please make an effort to call me back and resolve my issue as i have spoken to too many agents and they keep saying they will log a case. this is so frustrating!!!!
