Vodacom vetting department

I've app**** for a contract with vodacom 2 and a half weeks ago ,and in that time I had to go back and forth with the store as they kept telling me that they have alot of queries on the application. They then tell me that I dont meet the credit criteria . I was surprised as the previous agent told me that my score was excellent. I then get a call and they stated that they would need a letter from my bank as I was applying on my business. Gave all the necessary and then she calls as say that the vetting department had not been upgraded so she couldn't process my application. She then told me they sorted it out and that everything looks good. Today she calls and said that it declined. I'm really upset as all my stuff were in order and I own a successful business with an excellent credit record. I also have not received the reason as to why my application was declined. I've chosen vodacom only cause I've heard that they have the best deals . I'm horrified by the experience I'm facing right now with them.
