I am paying for a device that i dont have \*****\""

Recently discovered that I received a S6 13 days ago that I did not sign for or receive. Telkom bills me incorrectly every month and I been called to resolve this issue and nothing happens. I will be warning people on every social media site to not do business with Telkom the Westgate store especially. The store manager never moves out of his office to assist and they never have stock. I LOVE the mobile service but HATE the customer service. I never knew that having a cell phone contract could be such a pain. The amount of money that has been taken from me and never credited back into my account. I am very angry... The fact that you feel that you have the right to bill people what ever. I work hard for my money it gives you know right. I am not getting anything for free. Im paying for a service that Telkom is not able to give but i'm paying every month.
