I have had numerous calls from ITalk, when I return the call a recording says the call was not important, but give the option to remove your number from their system - this does not work! I took a call today when I came in from work, they claimed never to have called me, I asked to speak to a manager to make a complaint, surprise surprise anyone more senior than "Clinton" was in a meeting - I was pointed in the direction of the website to make a complaint! Clinton would not give me either a telephone number nor an address for me to contact them on to complain about the number of calls I'd had. Do not deal with them!
