Worst service ever

Bought a phone cash online with vodacom received my order confirmation and also my waybill no but now they failing to deliver when trying to contact their couriers they say vodacom didn't give any info about me address and contact details I must contact vodacom

When trying to contact vodacom on the phone number they gave me with waybill no they say its the wrong department I must find the nearest store and go there (I never wanted to go the store which is why I bought the phone online )I never expected this from vodacom
