Terribly Unaccommodating Owner

The owner, Faisal Khakoo, is not accommodating at all. Highly recommend not buying any deal they have on wikideals, in the initial terms and conditions it did not mention a limited amount of vouchers to be used in one booking. He said straight away I need to email wiki deals and speak to them and get a refund. I mentioned that it was for a special occasion, a 70th Birthday, still, not willing to accommodate. I was trying to explain that I would be willing to pay additional for the extra 4 people. He has a terribly rude tone which I informed him of and he said he will not be allowing us to make a booking.
