MTN not supplying goods as per the contract

I took out a new data contract with MTN on the 4th July 2017. The contract included the delivery of a 3G wifi router\hub which I have still not received! After numerous calls to the MTN support line I have still not had any feedback or word of the delivery...! Even after I made it clear that this was in breach of contract since I am paying for goods I have not received for 2 months!!! What is going on here MTN...? The next call will be to demand the contract be cancelled and I will go to another service provider ASAP.
