UPD horrible service

On 19 January 2022 UPS picked up my packages from Germany and since then I didn't receive any notifications regarding these packages.

On 11 February after waiting 3 weeks and not receiving my packages nor notifications I tracked the packages at which point it indicated that UPS abandoned them because they could not deliver.

After discussions with staff it was because UPS did not get my contact details from the seller but they had the delivery address. Instead of trying to get my contact number to arrange delivery or trying to deliver at the address specified UPS just discarded it.

On 11 Feb I was made aware of the taxes payable and made payment immediately. Then when calling again on 14 Feb Gren logged the retrieval for all 3 shipments. Another week has gone past since I contacted UPS and I followed up multiple times this week to make sure these items are being retrieved during this week's slot. I sit at the end of the week without my delivery again.

This has been horrific service and I would like to know what UPS can do to fast track this delivery that has been discarded due to the lack of proactive service to get this delivered.

I also send an email to the manager with no response: ***
