That is the problem, they previously had so many promotion upgrade packages flying around...double up speed bla bla...at the end they could mot cope up and do it for everyone, pity TM customer service has to deal with all the shit complaints. If they market with single standard price for each speed properly, this kind upgrade or not issue not exist. If people want higher speed, they just change plan to pay more for higher speed, that is all, why TM create so much headache?
