Bad customer service

I'm so frustrated by the bad customer liasion, I cannot deal. I called a number listed under a specific branch to find out what each Pedi entails, I was doing this on behalf of my 74 year old mother. The woman was trying to explain each, but there was so much screaming & shouting in the background that I could not make out a word of what she was saying so I said there is too much noise, I cannot hear you. She retorts 'apologies for the noise, but my dear you do know you phoning *whichever* department' so I rep**** that i was not her dear & proceeded to say that no I didn't know where i was phoning because i called the number under the branch details - not specific division or head office, etc, but she put down on me before I could finish my sentence. LOL. I called back, but no one answered so I called another branch number & asked for a customer service / complaints number or email, the woman s******ed, put me on hold without saying anything, brought me back, put me back on hold without saying anything then the call was disconnected. When I called back she did apologize which was fine. After some time of still not getting a contact email or number I then asked if the owner was contactable, I was told no which is somewhat understandable, but it was at this point that I gave up. If all the staff I had dealt with thus far with was so unproffessional & rude I wouldn't be able to bare it if the owner had the same attitude. I don't know what to say, such a pity.
