I placed an order for a personalised gift which was not delivered on the promised date. When I enquired at 16.00 on the delivery date (Friday) , I was told through an online chat that I had to wait until the following Tuesday for delivery since there were 'a few issues with (their) PER department' A crisis for me since the very special personalised gift was meant for an anniversary celebration the very next day.
