Hi. How are you? Imagine, I've just bought a new cell phone, so simple and very convenient. It had some problems with the battery,which had stopped charging. I had brought the cell phone to be repaired in a service center. The store assistant told me that the phone would be repaired within one month. Unfortunately, my phone hasn't been repaired yet, therefore I'm not able to call anybody.

good luck!
