Pathetic customer service.

I have a cellphone contract with Blu Label Connect, on the 19th of Feb I sent it to them for repairs and I was told it takes 7 to 14 working days. After 14 days I called them to check the status as i never received any call from them. I was told its still on repairs, but no one is giving me updates, no communication from them. I called again this morning I was told that it was sent to the supplier. I then asked to speak to the supervisor, she told me that its finished its just waiting to be dispatched but couldn't confirm when. Their stories don't match. I need them to tell me when am I getting my cellphone, I cant be paying for something that i don't have.
