Rude , put phone down in my ear

On 10 December 2015 about 10:45 I phoned the Sanlam Call Center to assist a client with a transfer , I spoke to Winnie Stuurman to forward me the required documents , her emails didn't come through , I kept holding and waiting after 17 min she was so rude said she can't wait any longer she will send it and then put the phone down in my ear , this is not very professional at all!!!
