I went to Vision Express and I had my appointment booked for the eye test, everything went well but when i went back in the evening to select my frames, i was told that i couldnt use my blue light voucher and that using the voucher was only allowed all in one transaction, however the employee that served me in the morning agreed to me coming back in the evening and use the voucher after paying £30, but when i went there they were not even coming to serve me. The customer service at Vision Express absolutely awful and i would not recommend it to anyone. I then went to another shop, which had brilliant customer service and got my glasses.
