Incompetence of DHL

I ordered a dress intentionally on the 13 of February 2018 using DHL as the shipping company, as I’m tracking the dress it said estimated delivery is on the 2nd March 2018, I’ve been in contact with them since 9am this morning trying to figure out when my dress will be delivered, I was only informed today that the dress has been held by customs and certain documents are needed, I sent everything that they needed as timely as possible in order to receive my dress today, Then I’m told I’m being charged a penalty because the dress was under declared by the sender, I didn’t argue with them as I desperately need that dress today,I’m also to pay VAT and Duty charges,I was willing to pay any amount required to get my dress released from customs. I have to keep calling them to get feedback and updates,as they don’t bother to call and update me, now I’m told the dress will not be delivered today and might take 7 working days or more and nothing can be done.
