Buffalo logistics collection department

I had a bad experience with buffallo logistics, I requested parcel return with Shein and they advised that Buffalo will come and collect my parcel, they sent me a message on Friday 04/10/2024 around 7am and I immediately reply their WhatsApp to advise them that I won't be at the destination and requested them to collect on Monday, and no collection was made. I called them during lunch and the consultant advised that the driver came to the premises and business was closed, I told her that no driver came to the premises because I advised them in the morning that I won't be at the destination. She advised that collection will be reassigned and on Wednesday, Thursday and Friday I kept receiving the messages that says they will collect the parcel and no one came. On Friday again I contacted Buffalo and the agent advised that the wrong driver was assigned to collect my parcel hence it hasn't been collected but now it will be assigned to the correct driver and it will be collected this coming week. I asked the agent that since they made an error on collection can't they make it a priority because I have been waiting for the whole week. She advised that it will be collected the coming and that's a priority, I told her that a it will be priority if it is collected on Friday and said it's not possible the driver can't come back for my parcel only he has already left to do other collections. I requested to speak to the Supervisor she said supervisor is not available and requested to speak to her manager she said she is currently busy and asked her to tell her manager to contact me and until today I'm still waiting for her call and the manager's name is Rennet. I wish the courier service could improve and service customers better, their way of pf providing service is pathetic... I will never recommend Buffalo to anyone.
