Unhappy

It's a pity there is no zero.First when I went for a lay bye I was given a stinking attitude by the cashier who wear sangoma beads,I went to collect on the 23rd of March and I returned 1 pair same time because it smaller my child's feet has gotten bigger.I was told I can not get a refund as I didn't have this long first slip.I was then given a voucher and told it is valid for 2 years,No one cares to explain the terms and conditions of the voucher.I get home and I find a slip,then I go back today and with both slips and am told we can't reverse vouchers.There is a better shoe I wanna buy next door now I can't because you don't reverse vouchers ,that I also did not have a choice but to get it at the time because I had no 1st deposit slip.I find that unacceptable and disgusting as a customer to be put through such,making non fruitful trips to your store.Your service sucks
