Overcharged billing and data not working

I took out a contract in August 2019 for R599, Samsung A30. Since August 2020, with no communication, telkom has been billing me twice the amount. I have gone from pillar to post with the dimwit agents on the phone and Facebook messenger platforms with no explanation or assistance. They even close the incident reports before even helping me. The dishonesty. In addition to that, the conditions upon which I took the contract have not been upheld by telkom. The FREEME 10G VIDEO and Music streaming data does not work. Netflix, even at the lowest video quality, charges from main data and nobody can explain It does not charge from the streaming data that comes with the contracy. Youtube too and Yes I have settings at the lowest streaming and downloading speed!!! I have since last year already when I got Netflix and still my mobile data gets drained when I use the platforms that I should have access to with the video streaming data!. Surely these are not the terms and conditions my contract with telkom is based on. Can you just honour your end of the contractual agreement Telkom?? this is **************** and *****!!. I cannot wait until my contract is up so I can part ways with this ********** network!!!! Appaling!!!!! I wish I could give zero because this one star is not even deserved!!!!!
