Extreme and utter disgust with rams service

I just want to voice my extreme and utter disgust with ram couriers. I ordered and paid for my simcard from rain on ye 28/04/20 and received my waybill no for tracking from ram on the 29/04/20. The parcel was scheduled for delivery on the 30/04/20 but it never came and by the end of the day i just received a message saying delivery was unsuccesful. Today the exact same thing happened. I tried calling their customer service number but no one picks up that phone. If anyone can assist please leave a reply Thank you
