Wikideal *******

I received Wikideal coupon as a Xmas 2025 gift - Spa treatment for 2 and Smash Burger, however when I tried to make a booking on 5th Jan for Jan at Spa (at Canal walk, Mood Beauty, I was told they are fully booked until March.. My coupon expires 5th March? I was told by Moon Beauty I must contact Wikideal to extend my coupon, they are only a service provider.. I emailed Wikideal twice, phoned them and thus far only received empty promises. What is the point in offering deals if you cannot use the coupon.. Total rip-off!
