Delivery is only a pipe dream

I was meant to receive a package on 5 September. This package was marked as "Delivery Failed - Receiver not available for Final delivery". When trying to query this by phoning your support number, the number is saying it is no longer connected. I got a response from the support email with the agent stating that my address is "poor". I furnished them with my full written address, a Google Maps pin AND a screen shot of the map in my area, clearly showing surrounding roads and my house. They stated they sent this information along and will revert when they have an update.

Today however the package was delivered to my parents house. This address was NOT provided to ANYONE at any time with my dealings with DSV. I would like a CLEAR and CONCISE explanation of how you found my parent's address - an address I have not lived at personally since 2014. Using this address in any capacity is a massive information breach never mind the fact that you delivered a package to a person not listed as the recipient and thus not authorised to accept the package.
