Technician slams phone in customers ear

I called in for assistance as I cannot get onto the internet. held on for over 44 minutes before someone answered. The technician was irritated and rude from the time she answered. She told me that I should know my computer better and that the fault was mine before I could finish explaining what the problem was. I then asked for her name and a reference number and she slammed the phone down in my ear.<br> <br> Shocking service. And with no name, she gets away with this kind of behaviour? Are these calls not recorded???
