Bad service from Property Maverick

I would just like to say i am disappointed in the service i have received from one of the agents of this company. His name is Riccardo Zappa he is very unprofessional and disrespectful. He was disrespectful and rude to my husband when my husband raised concerns about the occupational rent that needs to paid to us. Because we didnt get any help from him. We decided to get legal advice and he was swearing at the legal adviser and hung up the phone. I am so disappointed at the treatment i am receiving from this agent and company
