Not Happy

Did a online booking. Got the gear I paid for online. I coild not understand why when I was doing the opsticals my one sock kept on coming off. Only when my 1hr session was finished and I took the socks off I realized they gave me 2 different sizes. When I approached them about it they did not seem to interested and ask if I had worn the socks that I paid for. Now i am sitting with 2 odd sizes. Obviously yes I did and they just refused to do anything about it. I will not go back there In a hurry again. There locker devices was also not charged so I had to keep on asking to plug in the charger for me to gain access to my locker.
