I accidently put a £10 one onto my sim, when i want a £20 one. Thats only 300 texts and 100 mins, and i need the unlimited texts and 300 mins!! Is there anyway i can delete it off my account?? I dont care about losing the tenner, i really need unlimited and i cant buy a new one until the same time next month, and ive already used like 250 of my texts within 2 days. 
please helpp!!! thank you ;}
