Online application documents and waybill problems

I recently app**** online for a new phone contract with Vodacom. Coming from another service provider I hoped the service would be good. I received a phone call the next day with instructions to upload documents. This I did right away and waited for a week, after which I phoned and they told me that the documents weren't uploaded. I told them that they are, and soon after I received a notification that my application is pending. I struggled the entire next day with back and forth about the documents - they would tell me its not uploaded, then I tell them they are and then they confirm that they are. Finally after many phone calls later, I received an email that my application was successful. The courier phoned me to confirm my location and told me they would deliver the next day. I received a waybill number - but when entering this number the next day on the courier site, I get 'NO TRACKING FOUND'.I phoned the couriers to ask where my package is, and they tell me the waybill number is incorrect. I phone vodacom again who tells me that they'll phone me back...and I'm still waiting. The customer service is friendly and helpful, but this process is expensive and frustrating.
