Urbanic — Missing Product

Website:

www.urbanic.com

I've ordered 3 jeans from Urbanic but received only 2. I've raised this issue over their customer support, sent mails and continuously following up with them but they are not responding at all. It's been a long time now.
Never expected this from a brand like Urbanic.
I regret shopping from them.
Kindly assist me with this.
Thank you.
