Poor marketing strategy or a ****

We support the Peermont brand and use accommodation when we travel if Peermont hotels are available. We receive sms s & emails about special offers constantly. This week I received a birthday message ( my birthday is this week ) offering me a two night stay when I used the birthday promo code . They sent no promo code , I enquired about the promo code and I was told the message was sent out in error . Leaves a bad taste Peermont . Are these ****s or are you goading people to make bookings under false pretenses
