Terrible service and cashiers with no product knowledge. The cashiers are rude and have a bad attitude.

The staff or rather cashiers have been giving me a hard time redeeming wicode vouchers for almost two months now. Today was definitely the last straw. They have no clue whatsoever as to what the Ts & Cs of voucher redemption are and some don't even know what a wicode is. They waste your time and ask one another stupid questions regarding how the vouchers work. I asked for the manager and instead the cashier called Moshidisi who also happened to be very clueless and said she's calling the manager. So at this point I'm feeling very confused because who's is the manager? I got impatient and left because my over was charging and felt like they were wasting my time and money.
