No telephone manners

So I phoned in to get a price on tiles. She asked me form which company I phoned from. I told her and she said sorry she can't help me cause they don't sell to the public. I asked her since when they don't sell directly to us because we are also customers to them. Then she kept me on hold talking to somebody else saying stuff that I wasn't suppose to hear in a very bad manner. If she wants to say bad stuff about her customers she must please make sure the customers don't hear her and she must please close her side of the phone. I'm also in the retail business and this is really bad for a company name
