Xpressbees Logistics — boat earphones return

I have received a message that your agent will pick my boat earphones that are to be returned to the corresponding company but almost it's been one week yet he haven't even responded properly.
He is asking us to reach him even i tried to give it to him going to the address he mentioned but even then he said he is out of station.
I want him respond as quickly as possible it's already been a week.
By now i should get the replacement.
