Telkom swipe data

Tell on did some changes which affected some of their clients in that it cleared their data. This being on 3 August. A message was sent out to all the clients informing what had happened and "giving" them a g for 2 days. So they've acknowledged their mistake but are not willing to refund the data taken. 31 days in the month, taken on the 3rd, "given" 2 days, so what happens to the other 26 days? I've put in a complaint at their shop in Blue Route on Monday and given a number to follow up. It's Friday and I've been trying every day to get through to them but to no avail.
