Reclaimyourfees.com was launched by the charity Shelter Scotland on Monday, and 73 tenants who claim they were ripped off by agents charging unlawful fees made an average claim of £156.
Shelter Scotland director Graeme Brown said: “That over 600 people sought advice in the first 24 hours of the launch of this campaign further consolidates our belief that some letting agents are routinely ripping off tenants.”
