Poor Customer service and Arrogance of OPS Manager in PTA HUB

I am writing to express my dissatisfaction and disappointment with the shipping of my parcel, Waybill number 4J4JQV. The parcel was returned to the sender because the courier claimed they couldn’t reach the receiver. The last call was made on October 5th, and because the receiver was not at the address, no further attempts were made. I contacted the courier on October 10th to check the status of the delivery and was assured that the parcel would be delivered on October 11th. However, on the 11th, I received a message stating that the parcel had been delivered. When I contacted the receiver to confirm, I found out that the parcel had not been received. This morning, I called the courier to understand the whereabouts of the parcel and was informed that it had been returned to the sender. The consultant connected me to the OPS manager, who was unprofessional and impatient in resolving my complaint. He even refused to add the recipient to the call to confirm some information and hung up on me. I am deeply concerned about the level of service provided, especially from a leader who is supposed to resolve client issues. Additionally, there were no delivery attempts made between October 6th and 11th. When I called on the 10th, I was told the parcel would be delivered on the 11th. I would like to know why the parcel was sent back this morning.?
