Directorate of National Consumer Rights Protection (DNCRP) slapped fines of Tk 150,000 to some 10 to 15 stalls of Dhaka International Trade Fair (DITF) for violating consumer rights.
UNB says the DNCRP also realised the fine on spot.
Pranab Kumar Pramanik, assistant director of DNCRP, said they had fined the companies Tk 150,000 following visitors' complaints.
However, no written record was found filed with the office about the complaints and fines.
On Friday, DNCRP didn't receive any complaint from the consumers, said the assistant director.
According to some Facebook posts, they came to know that some food stalls are taking extra money from the consumers, but DNCRP didn't find any proof in this regard, he added.
On the other hand, Md Anwar Hossain, a salesman of a food stall, said that unlike every year, this year's management is much better.
"Our stall is not taking any extra VAT or service charge from the customers. We are selling food following the price list fixed by DITF secretariat," he said.
Md Imran, a cloth trader from Islampur, said that the quality of could have been better in comparison with its price.
However, several notice boards with the price list of the DITF secretariat have been hung on different spots of the fair to keep the visitors aware of.
According to the Consumer Rights Protection Act, 2009, consumers can file case within 30 days of the unfair incident and if the case is proven after investigation, they will get 25 per cent of the total amount fined by DNCRP following the complaints.
