I sent an order using the standard delivery on the 4th of February 2026 delivery date was the 17th of February 2026, till this day the sender has not yet received the parcel. I called them last week Friday and they said they would escalate I called again on Monday they said they haven't received any feedback from the courier I called again Tuesday they said they still haven't received feedback they will re-escalate I called again on Wednesday same thing and they said the supervisors was going to call me still nothing no call I am the one that has to do the calling and getting the same responses over and over I'm going to lose a sale because of them and their delays with no feedback. I'm asking them if it's only emails they use for communication with the couriers is there no way someone can get and get the parcel to get it delivered I'm so frustrated that's a lot of money I'm going to lose when the receiver cancels that sale, as he is also doing his effort of calling them almost everyday
