bad service inflated prices over 24 hours

so I send an enquiry to emerald on Thursday 29 September 2022 to find out about bookings and prices for the Aquadome I was send a price for myself and the kid R90 per person I arrive there on Saturday then I'm told it is R120 per person. i pay it as I don't want to disappoint the kids but then i email PORTIA CHALALA Sunday to enquire why I was charged more and she said nope prices changed. so emerald aquadome literally changed there price in 24 hours with no valid reason. Not to mention that i stood in a queue 2 hours to enter the place wow
