MTN cancelling contract without my consent

MTN is not delivering my router, and it's now 3 months down the line, now they are talking about canceling the contract, if I cancel the contract, I get penalized for that, so MTN wants to cancel it for absolutely free, I think it's very unfair. Furthermore, I don't want my contract to be cancelled, I want my router to be delivered. If MTN goes ahead to cancel the contract without my consent, I will never be the client again. MTN please deliver my router, don't cancel my contract, I opted to get a router because I have a need for it.
