Service Non-Delivery

About a week ago, I emailed the Defy Service email address ([email protected]) - looking to clarify whether an issue with the fridge I bought in July last year could be fixed & if it was covered under the warranty.

I've heard zero from them. ZERO. I sent a follow-up email & still nothing. Tried their WhatsApp number & it doesn't appear to even belong to Defy (it's been 1 tick on that message since I sent it).

So I guess my question is if Defy keeps those contact details for vibes, or just for appearances? And the follow-up question is whether they'll be responding to my email or not.
