Is my Z30 refurbished?

I purchased my Z30 on the BlackBerry store in November 2014. I received and activated the device on December; about 2 weeks later, because of some system bugs, I started searching device to see if it was refurbished and I found my "call summary" showed the device has been in operation since April 30 and my Total call time about 4 times what I had used. I called blackberry and reported it, but they're giving the run around without any explanation other than: my time was not set properly during set up or the phone is picking up my last sync with a previous BB. the fact is my previous phone was an iPhone and the PC that I used to sync the device is less than 6 months old. Is the phone refurbished?
