Dissatisfied with the service and the different feedback we get from different who work for the same company

I am not happy with the service we have been getting since we did an application.

every day we call and follow up regarding our application ,on the live chat which we always get the same agent named Elisa and she keeps saying the device we ordered is out of stock no concrete feedback is given , we still waiting.

when we called we got a different agent they tell us a different story that order was done on the 7th of February and turn around time is 10 days to receive a call regarding the delivery of the order which today is the 10th day still have not received any feedback as per the agent that assisted me on the call yesterday.
