[sirs-51]

Hello everyone, i need a help with my situation by someone that's more expert then me, i ordered a smartphone by eurocart4, i saw that this seller has good feeback so i decided to buy from this guys. I Paid almost 2 weeks ago and they gave me tracking information the 7th of November, so i m tracking every day on DHL website (that it's the carrier of my order) and they say "shipment waiting to be entrusted to DHL". Today it's 15th of November, more then 1 week and nothing happened, what you advice me to do?? Should i chargeback my moneys and buy the smartphone somewhere else? or i should wait more? I alredy sent 3 mails to the seller and they never responded.... I'm worried i'm getting scammed but i don't know, please help me. Thank you.
