Unfair Charges

My line with Telkom was disconnected because I was apparently 1 month in arrears which happened some time in April. I did not agree with this and disputed it when Telkom disconnected my line in July. During the dispute, Telkom reconnected my line for one day and then disconnected it again while the dispute was still in progress. When I realised that I had accidentally missed a month, I immediately paid up the outstanding arrears and my line was again reconnected. However, now I am being billed for 2 reconnections which I feel is unfair as Telkom chose to reconnect the line before the dispute was resolved and now expect me to pay for their decision.
