i found smarty unlimited data for £16 per month on a comparison site, smarty would not let me have it, i then found hidden in the ts and cs that it is for new customers only, that is unethical, it seems like LOALTY DOES NOT PAY!
i found the deal on kens tech tips, when i tried to buy it smarty just took me to my dashboard and no new plan added, the terms and conditions say for new customers only
