Edgar's Redsquare online purchase

I bought a Vivo Box online at Redsquare on the 15/06/2015 and it's was delivered on the 19/06/2015 but it's didn't have a voucher to enable me purchase a full size bottle of perfume,I phoned on the same day (19/06/2015) to inform them that I didn't have a voucher in my box and was told that Redsquare has problem with their suppliers as they don't have stock,till to date (25/06/2015),I have never received any correspondence from Redsquare online to update or issue me with my voucher,I'm so disappointed with the service I have received and do not ever see myself buying from them as its was the first time either.
