Order Delay - 4 weeks

I made an online purchase from Zara on March 12th but I haven't received any updates regarding the delay in my order. Despite reaching out to their customer service via Twitter and the Zara app chat, I was told to expect a response within 48 hours but I haven't heard from anyone yet. It's been nearly four weeks and I still haven't received my parcel. This has been a frustrating experience.
