We have been fatally scammed

We have been fatally scammed by this "agency". WE DO WARN EVERYONE before proceeding with them, as the problems never arise before signing the contract. It has been an absolute nightmare since barely a year ago decided to move somewhere else. Our minimum stay was over by then. They have completely stolen our deposit, leaving us in a critical financial situation after having a baby and both of us lost our jobs because of Covid. As an example, they quoted £900 for a job that can be easily done for £100 (we indeed found many contractors that can prove this). We have been completely helpless. Please, stay away from these unethical and heartless people, they can ruin your life as they did to us.
