Can you be anymore rude & patronising?

My friend and I were looking to rent a property with Connells. We found an amazing flat which we both fell in love with. Oh how I wish I hadn't agreed to anything!! The letting agent was nice enough at the beginning but as soon as we had agreed to having the flat it all went downhill. There was no communication between them and us, they failed to tell us about deadlines on our references and tenancy's. We had to keep ringing them to find out what the next step was, the women in the office are the most rude and patronising people I have ever ever spoken to. They all need a couple of lessons in customer service because I have never been so taken back by an estate agent being so rude and patronising. I had to email them to find out what the next steps are and all they did was email back saying you owe over £1000. There was no break down of fees, no pre warning that we will need to each pay this!! I am absolutely disgusted with this company!
