I opened a mobile phone contract with the 500 minutes and 5000 texts for £10 a month deal. I asked the salesman at Tesco Horwich, Bolton no less than 3 times if it would cost me more than £10 per month as the money was being taken out of my bank by Tesco. At all 3 times he promised me that £10 per month was the amount that would be taken. My bank statement arrived and guess what Tesco took £34, when I telephoned them I asked why did I not receive a text from Tesco Mobile saying that my credit was used or at or nearing the of my limit. I was told by the Tesco guy that we don't always send messages and I should have checked my allowance on line, meaning you have to check your computer to see if you can make a call, In my opinion Tesco are just (Edit). I have now closed my account with them and returned to ASDA.
