No answer or service no notification of duties to be paid

The ****iest service ever, no calls or emails from the collections department to say that there are duties outstanding how and where to pay it, they have my number and email on record yet the excuse is that my phone was off, I try calling the contact center and you wait for 20 minutes, after getting through, the agents puts me through to collections department the freeken call is dropped, damn useless, FM, no wonder companies like this just leave this country because the people doing this work are brainless.
