ELVOLINE is a scam & RIP OFF
Their promises are empty. They promise money back cancellations, then use a heap of tech jargon to smoke screen you so that they can "get away with" not refunding you.
And I quote "the European laws does not allow us transfer your money from reservation to reservation"
And excuse like "the automatic system cancelled the reservation " and "unfortunately we are unable to reinstate or refund your reservation" they replied in an email stating..." A cancelled reservation can not be reinstated in all circumstances... it is technically impossible."
WARNING - Dealing with these guys is chucking money away
