Fisher & Paykel Appliances review: online service booking

I booked an online service for my dishwasher, ref no: [protected] and received confirmation that it was on 01/02/18 between 7am and 12pm. Please see attached confirmation.
When nobody turned up, I rang the 1300 service line and was told my appointment was for 14/02/18. Why is there a discrepancy and why is it that I'm the one that had to rearrange my day to make sure I was at home when nobody was turning up. I am extremely inconvenienced and unhappy. I have rung another place to fix my dishwasher now.
