BAD SERVICE

I am disappointed by the service of Vodacom. I took out a tablet contract in September 2015. I went in a week ago to take out another two lines through Game Stores in Fourways and was told I needed to provide my banking statement s again. I am not certain why this needs to be done again before approval can be given. The Store staff also told me Vodacom indicated that I had the maximum number of lines and needed to submit this information. How is this possible when I just have one line?<br>
