Just gotten the latest Celcom fiber bill, was on 300mbps - 2 years contract, mid last month gotten free upgrade to 500mbps, however this months bill have to pay extra RM50-one off for the upgrade due to some pro-rated charges (Celcom Service advisor explain). After that next month bill will revert to old 300mbps charges, is it fair? can i raised to MCMC? as the free upgrade its auto opt in, only turn off its the extra RM50 which is one-off as advised.
