Delivery Failed Twice Already - Consumer Complaint for J&T Express Philippines

We have been waiting for 2 parcels to be delivered and the updates we have been receiving says that they were unable to push to delivery. We received a text saying that it was assigned to a driver. When contacted, the driver said they will call when it is delivered. But it was not delivered and the parcel was returned to their warehouse. Now we are trying to contact the driver but he is not answering. One last delivery fail update and it might be returned to seller and yet they are not responding.
