Contract issue's

I open and account with Telkom reasonly.unaware of the service I will recieve.I got a contract with them for WiFi and it is a certain amount must be paid per month but they have billed me the first month already since I've been with them and it got nothing to do with my contract agreement. They telling me things I haven't been told wen I open account.when I approached them first time about it they send me to different stores and all in store and call centre consultants giving me different information regarding my problem.its as if I shud handle my own problem I'm tired of running around and calling in and they keep demanding Money that u shudn be paying and I have been paying my amount I shud.I dnt understand hw their service work.wen u approach any person offering service they shud help u it feels as if Telkom my client coz I'm trying to solve my own problem which they caused me in the first place. I've paid my due but my service being suspended.and the billing I receive is a complete different account to my actual contract account I have.I asked them to cancel it and they told me I should email someone and wait for it to be cancelled .I'm the customer I pay my contract so why they telling me what to do and how.I've never experience such unorganized service in my life.I have called in plenty of times and noproper service being given to me as a custormer. I got to stress about Telkom consultants jobs they should be doing but feels I'm doing it for them.instore and via telephone consultants of call centre.please I need help I am not paying and billing caused that's not what I signed up for I paid only what my contract which was advertised by Telkom but they charging me more.that's robbing one actually if u think of it.I took it cause it cheap and works in my budget but now they *****ing everything up.I want to cancel the contract asap and won't ever open another account by them in future because of my first time experience by them.they can't advertise a certain payment for a contract and once you take it then they want to charge you and tell u about the system.that's **** what I see I wanna pay cause its a bargain deal then why lie about things on advertising.I'm so furious and dissapointed
