Sharp Logistics is Useless

My parcel is been on hold with them for more than two weeks. They sent me an email requesting for documents (ID, Proof of payment and commercial invoice) to release it, I sent them then the person that was assisting me kept on asking for a commercial invoice that was already attached, I just sent it again. Few days later new email came in with duties invoice and the charge was not realistic because my parcel is small and yet the charge is too much, I then rep**** asking why and no one got back to me and the whole team is copied. I then made payment because I am thinking let me get my parcel while waiting for feedback, till now the status for my parcel has not been changed. I am wondering since they ignoring the emails and they do not open the attachments on the email, did they see my payment. I am very disappointed on them :-(
