Appalling customer service

If I could give a zero star I would. I placed an order with shein about 2 weeks ago. And the delivery service said in the tracking system that try to call me and my order has been returned twice now. I DID NOT receive any calls. I have sent countless emails, tried to phone and WhatsApp Buffalo to no avail. It’s impossible to get through to an agent to just give me clarity on where my order is. Safe to say, I will never use Buffalo ago. In turn I will never use shein or temu again if this is the service I get as a customer. Absolutely appalling that the agents don’t answer emails/calls/whatsapps days later. I am still waiting for feedback.
