Total Ninja charging incorrect prices

Visited Total Ninja in Northgate during March 2024. Upon arrival, had to go through a rather lengthy registration process where all your personal information is required. Why is this, it is a kids play area so for what reason is the personal details of the parents required? Total Ninja can certainly not guarantee the safety of one's personal info. Then when I went to pay, the lady at reception tried to overcharge me for the socks. Price listed on their website is R35 per pair, but she charged R45 per pair. When I told her the price is wrong and listed as R35 on their website, she insisted that the "system" shows R45 per pair. I refused to pay the increased amount and after a long story she decided to talk to the manager. The manager then decided that we should pay R35. I ordered two pairs of socks so Total Ninja tried to do me in with R20. Now if they overcharge each client with R10 per kid, it means they make and additional cool R1 000 to R2 000 per day per branch. Easy money. With most of the items on their cafeteria menu also overpriced, they will not see us again.
