Why WD store 'Contact us' is always unavailable?

Hi all, I recently purchased WD Black SN750 but it’s cancelled because of difficulties in payment methods.
I checked my account balance, and it’s paid not refunded so I tried to contact with WD 100 thousands times.
Whenever I submit a query, then the screen shows this:


The service you requested is currently unavailable.

Does anyone have the same problem with me?

Yes, same problem for me.

I got a 20% discount code after my last purchase but it’s not working and contacting support doesn’t work…

…and sending an email directly to support just gives a “This is unmonitored…” and a referral to the non-working support case submission…

A phone call to support solved the problem after a few days.
