Lack of care and 2 months still waiting for refund.

My wife made a booking on bookings.com for Easter weekend 2019 to take us and other 2 x families out and away for the long weekend.We made the booking and paid for accommodation on the 16 April 2019. On the 18th April 2019 we phoned just to confirm if everything was in order because we would have left the 19th April 2019 very early. We phoned the accommodation and a lady that worked there told us that they do not have us booked at their place.We then gave her all the ref numbers but still she could not pick up that we were booked there and she also told us that they were fully booked. We then phoned booking.com and they said that they would look into it and come back to us asap. LATE that night we got a call from booking.com saying that unfortunately THEY made a mistake and that that booking we made was invalid and also that they couldn't give us that booking as the price was wrongly listed on THEIR site and also because the place was now fully booked. They then said that they would refund our money and didn't even care to help us in a other way in trying to get us another booking somewhere else. This property that was wrongly listed was listed for a whole week after we got "****med". So how many people lost their money on this deal?We got a mail saying that the money would be refunded within 10 Days. It is NOW ALMOST 2 MONTHS and we still waiting for our money to be refunded. This is by far the worst service I've even received from a bookings company. I went over to lekkerslaap and I've had the best ever service. Will definitely never ever use booking.com ever again and will also spread the word for no one to use it. So i would like to know WHEN will i be getting my refund and also with us waiting 2 months,has it grown any interest in YOUR bank account?
