Netstar exploits customer into large bills

Netstar kindly have my account reactivated,I owe you R396 +-3 installments that bounced due to new bank details not being update now you bully me into paying you R6000 to reactivate this is purely exploitation of good clients I have not run away I am willing to continue with my contract until 36 months but I am not going to pay you R6000 when I’m outstanding R396

Kindly credit note my account before I start publishing this on social media and all public platforms,R6000 Won’t equate to the thousands of clients that you stand to loose or consider other companies because they would be afraid of this same poor business ethics .
