DG toll intentinally updates the tag recharge after a day or two and thus does not allow carry forward the balance. I ahev updated my tag on due date of July 8, 2010 and they updated it on July 9 evening. however recepeit is of July 8 and yet my balance of last month has not been carried forward and it happens everytime you recharge. it is loss of 340-250/- Rs per month on an average.With faulty servers at their end why we as customers are liable to pay for more and get stuck in traffic jams
