'Indian' accented woman Claimed to be from vodafone offering me a 40% discount for being there so long. Then she said I am going to put you through to may accounts department.... stay with me... at which point I hung up. Why, if they wanted to offer me 40% discount would vodafone need to put me through to their accounts dept.. they have my billing details already. TOTAL SCAM. I have blocked the number.
