1. Always seek help, or complain, to the Tour Operator's representative as a first resort. They are there to help you.
2. Ask for a Customer Complaint form, fill it out fully and keep a copy for yourself.
3. If you can't get a form, for whatever reason, make-up one of your own and get a witness to sign it, along with their contact details.
4. If you accept payments, compensation on the spot, or sign anything, this will affect your rights if you are still unsatisfied.
5. Take photographic or video evidence of your grievance and get the names, addresses and telephone numbers of other unhappy holidaymakers. There will be strength in numbers if it is necessary to take your complaint further when returning home.
6. When you return home you must complain within 28 days, in writing, to the Tour Operator. It may also help to visit your Travel Agent and explain your complaint, asking for his support/help.
7. If the Tour Operator is a member of ABTA, there is a strict code of conduct for dealing with complaints that they must abide by. Ask your agent for a copy.
8. If the Tour Operator fails to meet the ABTA code of conduct then you can write and complain directly to ABTA and they are forced to follow up the complaint.
9. Never accept money or a cheque unless you are fully satisfied with the outcome.
