Contract ended a day early; me losing a whole lot of data and airtime

Since I've been having unresolvable disputes with Vodacom I've decided to close all my accounts as soon as I can afford to, while getting the ombud's assistance for my losses. I was able to put in a request to close down 2 lines for this month end, and guess what? Today was supposed to be the last day but surprise surprise...the lines are already closed, so I lost all the data and airtime I planned to use up today. Like seriously now...these guys are mafias!!
