Bad bad service

I have been sending emails back an forth, with just a simple request of my contacts to be cahnged. I called more that 5 times and everytime I get an answer of someone will call me back. Worse non of the consultants are able to help. The one who answers emails either is programmed to write one of our friendly consultants will call you back in less than 24 hours or that's the only thing he or she knows how to write.
