Consultants mistake cost me my super deal

<p> I went for upgarde on 06/09/2016. All paper work was done. I've been informed they do not have stock. I went back the next week. Still no stock. Went back again on 23/09/2016. (Two weeks). Phone is checked and tablet. When put on computer, deal not going through due to not confirming it in 7 days. Ive said to phone head office and explain. Was told not possible. She can give me other deal. R300 price difference to get the same. Proof once again Vodacom consultants (most of them- not all) incompetant to do work. I think it time to change. Second time this year consultant's mistake costing me...:(</p> <p> </p>
