On 16th Mar 2011, I bought a One Month Contract SIM from Tesco Mobile worth 10£ (500 mins & 1000 texts) over the phone. I used my aunts card because I had no bank account at that time. The SIM arrived on 18th when I activated it using an online procedure. 10£ of first month were charged upfront from my aunt's card.

On 11th I received an email of my bill that included the second month's contract as well. Thats when I came to know that they have set my billdate to 9th.

Since then, I have been in constant correspondence with them over the phone and emails and they do accept that I have been missleaded/miss-sold but but they are simply refusing to accept that a ONE month Contract has to end after one month even when No where on their website (from where I initially saw and selected this contract) do they say this is a rolling contract and the bill date will be set to 9th. I did not even receive any prior documentation from which I could have guessed that.
