Extremely bad service

DO NOT buy from Studio 88! I purchased a pack of socks from the Pavilion branch on Saturday. When I got home, I realised I had bought the wrong size, so made a special trip down to my nearest branch (Liberty Mall PMB) on Sunday - the cashier who I spoke to couldn't be more unhelpful and uninterested if he tried - he said they won't exchange it as it's considered underwear (this is despite the socks being unused, and still attached to it's packaging). He then said if I wanted a refund I must go back to the Pavilion branch. The staff in the store looked extremely unhappy, and it's clear they do not want to work there. On the till slip which I retained, it said I'm allowed to exchange or refund items within 30 days if they are unused and in it's original packaging - why do your staff not adhere to this? After looking at all the complaints for Studio 88, it seems many people have had the same problem with exchanges/refunds. I strongly advise everyone not to support this company.
