This shop has gone down hill and will close soon. Have printed e-voucher went to shop collected goods I wanted. At till voucher would not scan, supervisor was called she didn`t have a clue. The manager was then called after a good 5 minutes he turned up, now a que had formed ( very embarrassing ). He then tried to scan the e-voucher, still did not work. I suggested he enters the bar code number, as the casher had done this last time, said he wasn`t allowed. ( 10 minutes now had passed ) totally embarrassing. we were told to phone customer services. had to empty shopping on counter and walk away. then heard a discussion between supervisor and manager saying those numbers on the voucher did not look right. this was out of order, felt like a criminal . This is not the first time I have had trouble with John Lewis.
