Be very careful when or if you top up or collect your gold / silver prize on what appeared to be the 02 login web site after the obligatory hook a wretched duck and get your prize. Up popped a message from 02 asking if you would complete a very short survey. As a way of saying thank you they offer you a free gift, diet stuff / teeth whitening kit, weight loss pills just pay $2.95 postage. I signed up for teethwhitening kit, had the $2.95 removed from my bank account followed by another £128.00 the same day! My bank were aware of the scam and the company. The bank said they copy the web sites in this case 02 and add there own scam to it. Cancel your card straight away and transfer all funds but a few pence from the hit account. Keep checking your online banking (if you have it). I reported this incident to 02 who did not seem overly bothered and said they would look into it.
