Shocking service- lost parcel

Absolutely horrific service! I deposited a parcel into a Pudo locker to sell on Yaga. The parcel is now missing according to The Courier Guy and nobody gives me any update. I was told that Pudo would contact me directly as the public cannot directly contact them. I am yet to receive a call since last week. I have to re-register the issue and answer the same questions each time as they keep closing the ticket and I have to keep following up as nobody gives me any feedback. I have repeated my story on 5 different occasions and keep getting nowhere further than "we have escalated the issue and we are investigating". My parcel is now missing and nobody seems to care. Disgusting service, I will never use either of these companies again.
