Poor service Aramax & Pearl WhatsApp Agent

Poor customer service from Aramex & customer Agent named Pearl. They cannot find my parcel, Trackbill: ***. I received sms for the trackbill but they can't locate my parcel. They asked me to contact the sender to provide with required information. I asked what is the required information? Rude response from Pearl: "Your waybill does not track on our end 🫤" . There was no proper way of ending the WhatsApp conversation, she just disconnected. It's not appropriate to use these emojis "🫤" when dealing with a customer who paid for services & there should be a decorum way to end conversation, not just disconnect.
