bad service!!

This is now the second time that I went to the vodacom at the airport and had to turn back because they either give you the wrong stuff or like today sends my BIS to another number..the first time we asked for BIS they sent data to my fiance's phone I then lost that money.the second time now I gave them the number on a piece of paper and still they sent it to the wrong number..and I know like the first time the manager will have an attitude. I am really disgusted..cause my money was lost two times already now.
