Terrible Service- First time customer!!!

I was referred to Vodacom by my fiance as he has used their service for years. A few weeks ago a sales agent from Vodacom online called me and told me that I qualify for two Samsungs for an amount of R299. I told the lady that I would be interested as I lost my current phone, I gave her some of my details but as I was at work we couldn't conclude the sale. She promised to call me back and two weeks went by with no response (and no phones). I then decided to go to Vodacom 4 U a branch in Greenstone Mall. Paul assisted me and upon trying to vet my details, he found that I had an account pending and could not proceed with my application...I called the online people to have that one cancelled seeing as I did not get the phones- got that deal cancelled. And went back to Paul to continue with the new deal (he said that I qualified for a P20 Lite and that I am a Portfolio "P0420". Today when I went to check on progress of application he told me that my portfolio has dropped to "P0320" meaning that I qualify for a phone less than R170.00.... the online sales has obviously affected my rating and I would like this rectified ASAP please. This is unacceptable. my number is **********
