I recently "won" a £5 evoucher on my Sparks account. Went into M/S today to spend it and it wouldn't take it even though it said on the screen of my phone that if you'd downloaded it then it would automatically be taken off your purchase at the till. My daughter was unable to use hers on line as well. I was so disappointed as was my daughter. Why say that you've won something if you can't use it.
