Ask HN: Reaching Someone at Google UK

Apologies if this is not the right place or way to do this but I've run out of options otherwise.

I've ordered an item from the Google Store in the United Kingdom last week, which did not arrive. I've contacted the courier (DPD), who told me to contact Google (which I have done several times).

I've been trying to get a refund for several days now, but I can't get past whatever script everyone in Google support is following by phone/email/chat.

Is there any way I can get someone to actually seriously engage with my issue? At this point I keep getting told that they are "raising an investigation" but won't tell me anything further.

Thanks in advance, and sorry for the spam. I'm at the end of my rope in trying to deal with Google here.
