PUDO The Courier Guy

I am utterly disappointed. I have received the wrong parcel via locker to locker shipment with PUDO. I only have the pin and details to collect from that locked so I had to escalate it with The Courier Guy themselves. I have phoned 3 times today and still have not gotten a answer as to how to solve this problem. They keep on making promises that someone will phone me back but I have not received a call back. On another incident I shipped a fragile parcel and it was completely ruined when it got to me. I have not received a "I am so sorry for the inconvenience" for any of these incidents.
