THE COURIER GUY - LOST PARCEL AND NO ASSISTANCE

I have a Courier Guy account. I have sent numerous parcels with them to various destinations. On 08/10/2025 I requested a door to door shipment from Pmb to PTA. It was collected within 15 Minutes of creating the order. EXCELLENT SERVICE. 4 Company branded banners to our PTA offices. The receiver was contacted twice by one of the delivery guys to say his there to deliver. My colleague went out and found nobody. Within an hour we got a delivered notification. I tried to contact the numbers which called and there was no response. So I emailed support. The response I got was that our parcel was stuck to another delivery from Pmb and was under investigation. This was 15/10/2025. I have followed up daily with no luck. These are expensive banners and are needed urgently. Juan C at the courier guy support sees absolutely no urgency in this matter. This is really unprofessional and *********. We use their services because they are convenient and affordable. I have now been told by Silverton from the helpline that they can give me a response by next week Monday. VERY VERY DISAPPOINTING !!!!!!!
