Mega bad service - if you can even speak of SERVICE ...
I received an e-mail that my package had arrived ... curiously, I was at home at the time - but there was no trace of my package or DPD ... well, it wasn't the first time either.
So to the mailbox, check where he brought it this time (without ringing the doorbell first) - no information sheet in there, even with neighbors and Co.-NOTHING!
Called customer SERVICE - investigate the matter and report no later than 48 h - NOTHING after 48 h - call again (pay 0.60 again) instead of a friendly "hello" after talking to a computer for ages and being on hold was: "PACKAGE NUMBER PLEASE!" - well .. at least PLEASE ...
Then the information "Yes ... we are assuming a packet loss .. you have to report to the sender"
Aha...
1. Why do I get an email that my package has arrived if it has not?
2. Why do I have to worry about ironing out the error now?
3. What is meant by SERVICE ?!

Disappointed is no longer an expression ...
