Dissapointend

My partner booked at FRANS Guesthouse in Bloemfontein for the 4th till 6th of September, when he got to the place they said they already gave out his room to someone that was paying in cash,and the place was already fully booked,imagine the frustration he got to be stranded at night in another city,they said he should write to booking.com for his refund........he complained to Booking.com and they said they will refund him,it has been now 3months since he was waiting for the refund or atleast some communication from booking.com.......i am very much dissapointed in how booking.com conducts his business,he doesnt care about the wellbeing of the clients and their safety
