Lay-bye at Edgar's Active

On 2 December 2017, we did a lay bye at Edgar's Active Westgate. This morning when my husband went to the store, he was told that the sneakers are nowhere to be found. I called in and I spoke to the store manager, Linky, she said our sneakers are sold? I fail to understand how do they sell them because it was not even past the lay bye period. Ur customer services stinks...
