I always made tnt shipments the last shipment with cash on delivery I contacted them via LiveChat closing my face without leaving me to say what my problem is.
The problem is that more than 10 days have passed and I have not received the payment of the mark.
I make them work that I am a freelancer and I often make expeditions and now they do not make me explain the problem.
For me, they are not worth a star because they don't offer assistance after they pocket the money.
