the nerve

they actually deserve a zero rating. i bought a voucher last year and now when i want to redeem it i am told the experience is no longer offered. on the site you can see they have similar experiences but at a higher price than what i paid. now they want to me top up in order to enjoy the same experience. why am i made to top up when they decided to cancel after i made a purchase? i bought an experience and i deserve one, at the price i paid no top ups.
