PUDO - Ridiculous service and after sales service

I used Pudo for the first time last week. What terrible service. Door to Locker, I print the waybill. The fantastic driver collects the parcel. Receiver never received the pin. Parcel arrived at my doorstep this morning. They will not take responsibility for it and want me to re-do the delivery at my cost. Spoke to 2 different agents yesterday, one over email and the other over Whatsapp, both of them give me 2 different stories. I have been on the phone with them. First call, was the incorrect division. Second call I get told I am being transferred but then end up on hold for 6 minutes. Third call they tell me I gave them my address for delivery. Yes, to return the parcel. Just pathetic.
