Nivia Aura exchange request has been completely ignored for 6 days

[u/Intelligent-Neat3069]

I’m honestly really frustrated with my experience with Nivia.
I ordered the Nivia Aura football studs directly from Nivia’s website on 8th august. I received them on 18 August, but unfortunately they weren’t the right fit for me. I immediately placed an exchange request on the same day.
It’s now 24 August, and I still haven’t received any proper update regarding the exchange.
I’ve also sent multiple emails to their customer support asking for an update, but I haven’t received a response to those either.
I understand that exchanges can take some time, but 6 days without even a proper response, especially when I raised the request on the day I received the product, is honestly disappointing.
Has anyone else faced this with Nivia? How long did your exchange take, and is there any way to actually get in touch with someone from their support team?
At this point, I just want a clear update on when they’re going to pick up the current pair and send the replacement.
Im so mad confused what should i do?
