*******!!!!

I have a wifi home router contract with Vodacom and let me say im very unhappy with their service. I have noticed for quite some time now that the 200G data package we have does not last till the last day of the month. This was strange given that there's no one home during the week. I then decided to monitor usage and to my shock i discovered that, on the 28th of each month, Vodacom tgake away whatever data balance we have left. New data is loaded only on the 1st of each month, meaning we are left stranded during till then. We are then forced to buy data to survive the few days left before they load our data. This is *****!!!! why is the data taken on the 28th each month and not last day of the month!!???? We paid for that data and we should therefore be allowed to use it till end of the month. last month more that 100Gs was taken!!!! 100gs!!!! If their policy states that the data does not roll over to the next month, why take it before the month ends????? We are not getting value for our money and Vodacom is the only one benefiting, *****ulently so!!! Im so unhappy i want to cancel my contract!!!
