Worst agents ever

The worst experience I have ever had with estate agents. They lied and gave a not valid contract. The agent that showed us the property is the receptionist and not even an agent. Then the agent didn't put her name on contract only after we said the person showing us is not registered. They corrected places on contract and the parties did not sign where corrections was made. We are staying without electricity for 4months now and agents do nothing to assist!!! Worst lying people ever!!!!
