Former Coronation Street actress Wendi Peters said her daughter had to leave the Justin Bieber concert before the end and now "isn't as big a fan as she was."
Twitter user Nicola Gray said her daughter arrived home at 1.30am because of the star's "laziness". She addressed another tweet at the O2 arena demanding a refund of the £68.25 ticket.
Justin bieber should be ashamed my daughter finally arrived home at nearly 1.30am cause of your laziness... Fame has gone to your head boy !
Another mother said it was "awful how late he was":
