Buffalo logistics failure in communications

Absolutely shocking client communications from your company. This is now the second lot of items that we can’t track. The last two orders that have been a disaster to track and get sorted out! I paid for items on Shein on the 2nd February, once the order was placed a clicked on the expedited or urgent delivery option, the items were picked up for international shipping the 5th , duties paid the 6th on the day the invite was sent, only shipped on the 9th … and now two days later it’s still “being shipped” somewhere , they can’t tell me where. Consultant had terrible signal or quality of the call, kept breaking up the call, got very rude when I asked when it would be here as my other packages from Temu ordered the same day have already arrived two days ago with Fastway couriers. I asked to speak to a supervisor, was advised that’s not possible as supervisors are out, asked for name, reference number etc, no they can’t give that out, I can have contact details or email for supervisors. How does a company handling so many items not have a supervisor on site to deal with issues??? In December already your call centre admitted that the WhatsApp line is too busy and had a backlog which they couldn’t catch up with.
