Hi there, can someone call me back? I have been trying your CC number but it is constantly busy. To cut a looooong story short, I bought a phone on your website on 30 March, sent it back because it is locked.
So now, I want to know if you have received it (sent it last Monday 23April and I will have a phone back that works !!!
I have exchanged so many emails and the service has been inconsistent, very poor, contradictory
My order number is ID158112
Waiting to hear from you URGENTLY!
