Poor service delivery

I have ordered a parcel from Temu. Temu used Fastway Couriers as their preferred courier company to deliver my parcel. Fastway sent me a message on 27 Dec to say that my parcel has been picked up for delivery. For six days I have not heard from Fastway. They do not answer my calls, mails or What's App messages via their own app. There should actually be a zero star rating for this company. A week after this order I placed another order with Temu. This order I have received two days ago via Temu's other courier partner. If I do online purchases and the company uses Fastway as a courier I will not be buying from you. Fastway your service delivery is absolutely poor. I do not understand how your doors are still open for business with such an approach towards your clients and service delivery.
