Worst experience and insulted from HR - Mobility Engineer Innova Solutions Employee Review

Once direct contact person left the company .whole month no one there to contact , account manager moved to another position n got automated reply with the person to contact . Then after that contact person saying I am not the right person to talk . I keep calling n keep leaving voicemails n emails . After 1 month I lost my patience and got mad over the email ..bingo right a way reply to my email n saying please control on sending nasty email . Thing is who made me to do that ?? Then account manager putting other person in cc and calling me arrogant . The worst experience ever . I can share whole email thread here .
