I know because my office plan is also now showing 20 gb top up . I have 80 gb fup. I will post the pic tommorow . My guess is that since they have lowered their rates in my area so instead of lowering my bill they are increasing either speed or fup and since in my area speed cannot be increased so they have increased my fup . Just my wild guess. But I am keeping my fingers crossed and waiting for this months bill to generate. I hope they have not increased any tariff on that.
