If I could give them no stars I would. Cancelled the sim I'd purchased for my son on a one month buy now cancel at anytime agreement online. As he'd turned 18 (was willing to pay for his own phone) it turns out that if you dont phone they automatically renew! Without your consent. And sign you up to a 12 month contract. I've now been charged a late payment fee and now I have to pay for a 12 month contract I'm not using. Phoning them is infuriating! I was passed to 5 different people. They try to take direct debits 7 days before due. Or at random times. Please avoid this company at all costs.
