Staff are rude and unprofessional

Your call centre agents are extremely rude and unprofessional. I don't really care to receive phone calls from you in the first place but, when I say I'm not interested, they can at least say "Thank you for your time". Instead they just hang up without saying a word. It has left a negative impression of your company and I would never consider using Clientele for cover in the future. Train your staff to treat prospective customers better!!
