eDreams complaint: Reservation canceled with no notice

I booked a flight with return trip from Barcelona to Pula. Although I had received a ation email for the flight I found one month later that the return flight had neither been ed nor canceled. When I got in contact with Edreams I was told that the reservation could not be fulfilled because there was no space available on the flight. To my surprise the flight I originally wanted to book was still available on the website, it had just gone up to more of double the price. Edreams told me to buy the same flight again at the new price, paying for the difference while waiting for the refund of the original flight.

I was truly shocked by the indifference and the lack of solution of what Edreams calls customer support. Some days afterwards the very same thing happened with two flights I booked. One flight went through the other one was cancelled but still available on the website. It looks like a very strange business practice, combining partial cancelations with a complete lack of refunds or solutions.
