Awful back stabbing company - avoid! I was in Asia for 6 months and needed to cancel an out of contract sim card. They would not allow it, so i just cancelled the DD. They then tried to chase me for money and got the debt collectors involved for 30 pounds. Funny, since I was out of contract. They have caused my credit rating to drop 3 times! Despite me ringing up and sorting it out, they continue to have me black listed. I have now lost over 200 points out of 700 on my credit score. Literally can't get anything on credit anymore and I've spent the last 5 years building it and saving to buy a house this year. Over 30 pounds... which I shouldn't even owe. Stay clear!
