Problems with Google cache

[Luigi Donatello Asero]

A long time ago my one-man business had also the domain name
www.italymap.dk
I did not want to renew the domain name and I am not interested at this
domain now either.
Someone else seems to have bought this domain name
and have redirected it to another one.
No problem for me so far.
The problem might be, however, that Google still keeps the old cache so
that users see the
name Scaiecat Spa Gigi when they click on the page which belongs to the
domain name
https://www.italymap.dk (although neither my one-man business nor I as a
private person
own the domain name and the site)
The only website which my one-man business Scaiecat Spa Gigi
has now is
https://www.scaiecat-spa-gigi.com as I tried to make clear on
some of the pages on my website
for example on https://www.scaiecat-spa-gigi.com/sv/valkommen.php

(note with https to show the identity of the page)

However I wonder whether the results which Google gives using the old cache
cannot be misleading for the users and whether it had not better update
them...
Here is the link which let me find out about the redirect I told you about
http://www.google.se/search?q=semesterbostäder+på+Sardinien&hl=sv&lr=&start=10&sa=N
Any suggestions?
