Phone etiquette - lack of

I phoned a garage about a quotation.  This is a transcript of that conversation:

After about half a minute a young lad answered to a crescendo of loud music and car noises.

"ALLO.  Oo ja wanna to speak to?"  I gave my request.  

 "Oo?  OO?   'Old on **bleep**, I'll see if 'e's in."

 

 

 I chose not to "'old on." and put the phone down.  something else that annoys me is where, when making an inquiry Somebody'll groan over the phone and ask you to: "Bear with me."
