Appalling service

I went to Vodacom Middelburg mall 2 weeks ago to apply for a contract and Natalie Christians assisted me. I asked her how long a business application would take and she said a day so I should come back the next day. I went the next day and she said it is in process she will call me. A week went by and she was still quite, I called her and she said she will call me back, I went to the store and they said she is not in. I called the store and she said she will have feedback in 5 days (into the next week). I asked why is taking so long and she said she will call me back. I went to the store and spoke to a different lady to check status on application and I gave her my details and she couldn't find anything. I told her who I gave my documents to (Natalie Christians) and she asked her what happened to my application and documents, she said she threw them away. So much of my time was wasted I am so disgusted with her
