I will make you guys famous for the worst possible service ever!

Another week has gone by, i have not even received a response to my email sent to Talia and managers copied on the mail. The negotiator was meant to call me one week ago and i am still waiting. I receive a response telling me that my complaint is being looked at and someone will call me, i am still waiting since day 1. i am now prepared to drive to your offices to have this sorted. What will it take to get anyone to pick up the phone and call me? Third party claim against your client - Jasmine Russell - YKK044GP
