Worst experience I've ever had with a travel company, sold flexi date option which it had no intention of honoring despite a week's notice and the policy saying they needed a minimum of 24 hours notice. Despite repeated attempts to contact them through a variety of methods, I have had zero customer service to resolve this issue and have lost several hundred euro on this. I shouldn't say 'lost' - I consider Opodo to have stolen the money. An absolutely unethical company. Avoid.
