YouTube does not care.

I am a paying YouTube customer who has been harassed by a guy for the last week, i have reported his spam of insults on my video and comments on other videos and for days YouTube did nothing. I then contacted them trying to get my issue sorted, which wasn't happening through the means that YouTube offer. After speaking to YouTube support I was told my issue would be resolved... 3 days later i am still sitting with the same problem. I have no intention to renew my subscription and i will be making sure that non of my friends or family bother either. YouTube does not care about it's customers.
