No answer at Centurion store etc

On Saturday 17 Oct I went to the centurion store to get a fixed line look alike because I was incorrectly informed in Septenber that my line can be relocated. Found out there's no cables. Consultant processed payment for deposit incorrectly and took until 20th to reverse. She was helpful but took over two hours last week to get the phone and service activated. Came back today to pay my deposit. Store not open at 8am website states open mall hours which is 8am on Sat. I'm sick and in pain and can't stand outside the store until they open. Not open at 8:50 still. Can't come back to pay deposit. Need answers on how to buy additional data on account (needs to reflect on account for business purposes) website not helpful. Need help to check my balance. Using too much data. Wanted to pay my account but charged for October even though I had no line until 17th. So many issues and nobody is reachable.
