3 Mobile Phones (Third Generation 3G Mobile Network)
I am being charged even though i cancelled my account

I would like to complain about 3 mobile phone company. In November/early December. I informed 3 mobile phone company that i wanted to cancel my contract with 3, they told me that i couldn't cancel because it was a 18 month contract. I told them that i still wanted to cancel my contract with them. They informed me that i would have to pay till the end of the contract. I asked how much this would cost and they said £114.00 i paid the amount asked. Then in jan i received a bill from 3 stating that i owed £111.00 i tried to explain that i had already paid the final amount they asked for. They now said that the final statement for my account was £111.00 this would be the last bill for my phone. Mean while i had received a mobile phone over the Christmas period that i had never even asked for. I phoned 3 they said that they never sent it and i had to get into the company who sent the phone but the contract was apparently from 3. I got in touch with the company that had sent me the phone i explained that i have not ordered the phone and i no longer had a contract with 3 and i did not want to go with them again. I sent the phone that i never took out of its packaging back to the phone company. Again i got a bill from 3, when i contacted them they said that the bill was for a new phone that i had received over Christmas, i tried to tell them that i had sent the phone back but they told me hat the company that had sent the phone had not informed them (3) so the contract was still open. I got onto again the phone company that sent the phone they told me that they had informed 3. Now i have debt company's phoning me all the time saying that i owe 3 £149.00!! I dont know where this amount has come from. I need help please to sort this out, it seems to me that its me versus 3, the mobile company, the debt collector i cannot take it any more. I am disabled and suffer from depression and this is making me even more ill. I cannot afford to pay anymore money to 3 as far as i am concerned, i cancelled my contract with 3, i did everything they asked me to do, i have paid them £215.00 approx. I dont know what to do now. Thank you Mr L Whiteley.
