Well the reward vouchers arrived and off DD and I jolly well go to Tesco to change them on their double your voucher scheme,we did our home work and with the help of one customer service advisor we decided on what we where buying,the vouchers totalled £80.00 so we where careful to spend the correct amount as if you do not spend in FULL £10.00 or £20.00 amounts you loose the difference,so yes we where very careful,when we got to the till there was £7.00 to pay I did not comment on this as the queue was massive and we had to get to school,only at home did DD say she thought the bill was wrong,when we looked at the bill we had been overcharged for a game that was priced at £9.97,it had come up as £15.97 so the problem was there,I telephoned tesco and told them of the problem and informed to bring in next day and a refund would be issued,arrived and the price had been changed on the shelf where the game was on display,so no refund,I was told I must have made a mistake,why would I make a mistake if I am buying in very near £10.00 amounts so as not to loose the value of my vouchers,ie if I had chosen at £15.97 I would loose£4.03 in voucher money so I am not that daft yet.So Tesco will not refund will have not replyed to e-mail and twice telephone CS advisor cut me off on the phone,so TESCO you get no more business from this family or my extended family,it's off to the new Morrisons complex for me and mine. Sorry post like war and peace.
