No response - parcel at customs

My parcel arrived on the 24th January at customs. Now, almost a month later no one contacted me to inform me on the process of how to proceed. <br> <br> I inquired electronically at Dhl as to why my parcel is not being cleared at customs. The following day I did indeed receive a response via email that someone would contact me shortly. I could not take the said call For documentation reasons I asked them to contact me via email and explain the situation to me through another electronic inquiry. <br> <br> Furthermore, I tried contacting them telephonically a few times, on a Saturday. When choosing the third option over the phone, I got redirected every time to a prerecorded message stating their office hours, including that of Saturdays (which are from 8:00 to 16:00), and that I should contact them during their office hours only. I tried again today (Saturday) and got the same response. <br> <br> Last week I managed to get through to them during the week and my call was transferred to someone else. This person informed me of the person's name responsible for my case at customs and I was told that that person would contact me later that day. It has been more than a week now and I still did not get a call.<br>
