Total Access Communications Company, operator of DTAC mobile phone service, has been asked to explain to the National Broadcasting and Telecommunications Commission (NBTC) over two incidents, said Takorn Tantasith, NBTC secretary-general.
The first incident involves the recent seizure of 50,000 unused DTAC SIM cards by customs officials in Aranyaprathet district of Sa Kaeo province.
The second case is about a complaint from a customer that her mobile phone signal was cut off on Dec 7 because she ran out of credits. After checking with DTAC, she found out that she was charged 461 trillion baht for phone service.
On Friday (Dec 8), DTAC issued a statement clarifying the complaint of overcharging and the suspension of service of the customer. It said that during 5-6 pm on Dec 7, its system developed technical problem, making it impossible for domestic customers to make phone calls occasionally, but they still can receive calls as normal.
The company said technical staff tried to fix the problem as quickly as possible and they managed to restore the service within 6 pm, adding that the mistakes in service charges had also been rectified on the same day.
About 100,000 customers who used a monthly package were affected by the technical glitches.
The company offered an apology for the service disruptions and offered to make amends by offering a 50-minute free mobile phone use for three days and free internet of 500 MB for one day for affected customers who will be later notified by the company.
