Can I just confirm, I spoke with the store manager who resolved the issue with the overcharging for the monitor. However, I still had to return to the store and also at the time when purchased we were offered this at €99 as there was a sale (and was advised this price would be honoured if it went up) and then were charged €119 last week, not because it was more expensive so there was no confusion on this from our side. It is a stressful (and expensive) time for new parents and parents to be and just hope that it does not happen to anyone else in the future.
