No Feedback

About a week ago I wrote a complaint about DHL and they promptly responded and assured me they would treat my complaint with "utmost importance and would revert back to me with concrete answers".

Since that response, nobody has bothered to even give me some sort of feedback or anything...seems like the only way to get their attention is by writing reviews all the time because communication with customers is not taken very seriously.

As a company that deals with customers/clients on a daily bases, this is just disappointing.
