Helpless and plea for justice

Blue label connect company always writes that they will solve my problems here on hello peter but when they call they are not offering me any solutions they are demanding me to pay 6000 for then to cancel the contract and now I don't know what to do because i feel harassed and helpless about it....the phone that was given to me is with their company and on the other hand they demand me to pay them money for cancelation or the contract will still go forward meaning they want me to pay every month although their phone is with them..I really hope someone can help me to get justice from this company because they say something else n do the other
