1. You selected the wrong one
2. You have not activated them.

It is both your fault. 

If you did not take the time to select the right one, you most likely have to start all over again to find a new one

If you did not activate them, i.e. making them hungry supporting them etc They would not perform. If  not too late, try to reactivate them.

Note. Do not try to get them to sell like you do on your domestic market. Adapt your activities to the local market.

Make sure they can make money and give them support. Then you will see the result.
