HP Non-Support on Reverb 1

I have a simple question. I own a HP Reverb 1 and would like to know if I can exchange its (inflexible) cable by a more flexible G2 cable and where I could potentially purchase it separately, if available.

I went to HP Support where I am promised Support via "Chat, Phone or E-Mail". I understand, I need a HP account and have to register my device first. Fine, I did this, the device was recognized and the remaining guarantee was displayed.

Next, I expected the named options for "Chat, Phone or E-Mail", but no, there are:

(i) Online-Support

(ii) WhatsApp

(iii) Messenger

(iv) Phone

but no E-Mail

(i) Expectedly, the electric supporter is a joke. I'll resign from displaying the dialogue. 

(ii) Is taboo for me, sorry. I'm not going to feed Mr. Zuckerberg my data.

(iii) Says © Facebook 2021. Zuckerberg as well. See (ii)

(iv) Has a button "Get the phone number". Clicking it does NOT get me a phone number but a contact form where I could input my phone number. I did this and got a (non-reply) mail with a case number, but no number to call back. This was 5 days ago. No further action so far.

That's the worst customer service I enjoyed so far, and I clearly see HP does NOT want to interact with their valued customers.

Does anyone have a suggestion how to proceed?

Thanks and kind regards, Michael
