Nothing had been done to fix the problem since about 200 legal tuk-tuk drivers staged a protest in parkland opposite Phuket Provincial Hall in Phuket City on June 26, Damrungtam officials were told.
Phuket's Land Transport Department had promised a crackdown, said tuk-tuk drivers yesterday, but instead the problem had grown worse.
''Instead of 50 or 60 illegal tuk-tuks, there are now about 100,'' one of yesterday's delegation said.
The illegal tuk-tuks are undercutting the business of registered legal tuk-tuks in Patong and Kata-Karon, Damrungtam officials were told.
Back in June, protesters questioned whether bribes were being paid to allow the illegal tuk-tuks to function without interference.
Yesterday's complaint is to be passed on quickly to Vice Governor Jamleran Tipayapongtada, who takes charge of Phuket's transport-related issues.
The drivers warned that unless there was ''justice'' within 15 days, they would be forced to take further action.
