Vitality baby

I'm so disgusted with vitality baby, my 10% babies r us discount is not working, last week I went to purchase my baby travel system and camp cot only to be told my 10% discount code is invalid. So I walked out the shop got in touch with discovery the next day and they said they would look into it. A few days later I get an email to say the code is active..so today I go back into the store to purchase the items again only to be told.again that the code is invalid. So on two Occasions I have been made a fool of because it's not working!!! I call into the call.centre to sort it out right there and then and of course I can't be helped. It has to be logged again!! Its disgusting that you can put unnecessary stress on a pregnant woman!!
