LBC TRABAJO MARKET -Asking to pay another Shipping fee kahit Branch FAULT na namisroute yung package - Consumer Complaint for LBC - Head Office

My seller shipped my parcel last August 5, 2020 at LBC Trabajo Market Branch. The package was bound to Batangas. The details of its LBC San Jose, Batangas branch is very clear on the Tracking Receipt. I was surprised that when I tracked the package after a few days, it was in Occidental, Mindoro. I called the attention of my seller then I called the attention of LBC through its Customer Service. It took them 3 months to return the package to the Origin Branch. In fact, as of writing, today is October 21, 2020, and the package still has not been returned to the Origin Branch (LBC Trabajo Market) My seller and I continuously call and went personally to the branch involve with those three months that already lapsed. At the LBC Trabajo Market, the staff there said the we should shoulder the Shipping fee to Batangas when the parcel has been returned. Why do we need to pay another cost when in fact, it was clear from the receipt the we indicated the correct shipping address and it was their fault they misrouted the parcel and brought it to the wrong destination. They should be liable for the cost of the re-shipping to the correct destination, not us. It was a fault on their part and it should be charged at their expense. Why transfer the liability to the customer? Is that the kind of customer service that they want to convey? It's not just and very improper. The staff there did not even said sorry for their fault and yet they want us to pay again?
