Not honouring specials advertised

If you going to advertise specials at least honour them, if you going to advertise a customer complaints email address at least respond when it is utilised on 4 or 5 occasions. Why should i embarrass myself, waste my time and hold up your queues cause your systems are not accurate. On five separate occasions I have lost money due to you not honouring your specials and ontop of that not even bother to reply to your customer complaints email address (once i received some generic response with no outcome). You have lost another loyal client, no wonder your customer index score is so low.
