Very bad delivery service - drivers lying that customer cannot be reached

Very bad service at Game Wonderpark, which is serviced by Wumdrop. Drivers do not want to deliver to Centurion, so they keep sending the goods back to the store and lying that I cannot be reached. Goods were ordered over a week ago. It was returned twice to the store with the reason being that I cannot be reached. The Drivers are lying because no-one tried calling me. I also was in contact with the one Driver via whatsapp and sent him the access code to get to my house. He read it but did not reply, but told the store that my phone was off.
