complete disregard for customer service

Failed in every way possible to notify me even when he promised he would over a dozen times. I called 60 odd times trying to get hold of him, when he promised that he would call me. He called me once when the problem was initiated (13 days ago)and was meant to get back to me. Was sure to state in his emails that he would call and has never done so ever since. Tries to pass the buck onto me by being shrewd and twisting everything that I say or ask. I am completely intrigued and astonished by the man who is supposed to be in a supervisor position at the voice of the \ customers "department. Really don't see how"
