I wonder if anyone else has had this humiliating experience at Tesco's. I had recently doubled up on-line my Tesco vouchers to use in store. I received them in post but today in Beckton (London) Tesco the vouchers got refused as fake! Apparently they have a circular dated 26 May 2009 that fake vouchers are in circulation similar in description to one I had been sent out. Beige/cream in colour, without customer name or clubcard number. What really drove me up the wall was the attitude of the staff and refusal of duty manager to see me. I am fuming.......!
