OMG. I recently called to the company CROYDON DENTAL. I wanted to make the appointment, but the rep was angry and rude. She spoke with me in horrible manner and afterwards she refused to help me and simply hung up on me. It was really unpleasant and rude. Please leave comments about this company, because people should be aware when they deal with such irresponsible and dishonest people.
I have a strong feeling that the "rudeness" was being told "no" and not telling you what you wanted to here. You are forgetting to mention you were rude which is why you were hung up on.
