I hope is that Genies only accept jobs that they can commit to attending within 30-60 minutes and not let the customer down.  We understand things do happen.  We ask that you are courteous and call the customer to advise, either scheduling another mutually convenient time or advising that you need to cancel, with a reason and they can book with another supplier.  Please do contact us with any issues.  We hope that this will be a one off, however we would need to discuss this with you if it were to happen on more occasions and it may mean that we would have to part ways.
