Given customised numbers but incorrect

I went into the branch and I was offered to get customised numbers as I needed 7 sim cards rica'd. Vincent advised that they will all have the same number and the last 4 digits can be changed. I then chose 0001 - 0007 as the customised numbers. I used one of the sim cards to get the number and used the formula that they will all have the same numbers except the last 4 digits which would all be different. I then handed the sim cards out to my workers and transferred R1550 airtime across the 7 cards from ABSA internet banking only to find that each number was in fact different and only one person received R150 airtime putting me R1400 out of pocket.<br> <br> I called Vincent who was unable to assist with any feasible solutions and I have basically just lost that airtime. <br> <br> This is most unfortunate for me it seems.
