No Response

Last year in November I upgraded my contract to a Black Friday deal, then at the same time I asked the person that was doing it for me to open up another contract with the same deal. There was an issue with the new contract and the lady I dealt with said that she would phone me back in 10 minutes to then open the contract in my name as the upgrade was in my brothers name. She never phoned me back, I then phone a couple time during the week and left several messages but still no response from her. Then I phoned again a few days ago and the person I spoke to said they would phone me back to sort out the problem, and nothing. I’ve since phoned 3 times and never get through to anyone, I’ve spent atleast 30 minutes per call waiting for someone to answer. I cancelled my previous contract so that I could open this one up, and now I’m stuck with no phone number.
