Sun Broadband Wireless Modem purchased in Sun Shop Cattleya Condominium Makati was refused replacement. The modem does not function on the laptop of the buyer but according to Sun shop it functions when they test it. The complaint is the buyer cannot use the modem in his computer thus it should be remedied by the shop. They have not given it a solution and when asked to refund the item since it still is intact with its free load P180, they said it does not belong to them anymore and is the problem of the consumer that it cannot be used. Where do we go to complain so that the modem can be used or replaced? The item cost P1, 890.00 and they have not even recommended to check the configurations of the laptop of the buyer so that it will work with the modem that they sold.
