At 11:30 AM, our emergency WhatsApp support received an urgent distress call from the procurement director of a major surgical instrument manufacturing unit located on main Daska Road, Sialkot. Their primary Dell Latitude 5420 workstation containing custom export shipping manifests and bill-of-lading documents had suddenly gone pitch black with a burning smell following an industrial generator switchover.

Having an engineer arrive at our Daska Road facility with real chip-level soldering gear instead of telling us to wait 4 days for a replacement motherboard was unbelievable.
