Got my contract with this company, when I was setting up they asked me for the name of a sibling which I thought was odd but didn't think too much of it. The account has been set up with the wrong name (the name of my sibling), wrong date of birth, and wrong address. Result is I still pay the bills but I can't change any details on the account (like changing my 3 contract). Been trying to call the company on 0780 111 0157 but I sit "in the que" for between 4 and 8 minutes each time listening to "your call is important to us, please stay on the line and we will transfer you to the next possible agent" then eventually I get "There is no one available to answer your call" and the system hangs up on me.
On the rare occasions dealing with the call centre agents in the past (when originally setting up the contract) I found them to be difficult to talk to because they have a very poor grasp of English and strong accents. I am currently working with "3" to cut them out of the loop.
I suggest looking at http://www.ciao.co.uk/themobs_com__5646021 for other people with similar experiences.
