Misplace of laybye clothes

I did laybye somewhere in March 2018 where by it was due in May 2018. What happend is that when i went there to make payment a teller made an error in that they have to re do the capturing on the system. Thats basically not my complain. The issue here is that on the 13 April 2018 i went to pay full amount and exepecting to collect the laybye. Quess what i was told in the store that they cannot locate my laybye because the person who capture it did not put a shelf location. I politely went back to the office since it was lunch time. It appears to me that the laybye is no where to be found .Now they r telling me of doing stock taking whereby there is no guarantee of getting that laybye. I m very much frustrated as at the stage i dont want a refund but the clothes that i have selected for my daughter.Today i was supposed to have made another laybye , due to that i couldnt cos what if the same thing happened again,someone must take responsibility of his or her action asssiting me to get the clothes. My humble request is that issues be handle as a matter of urgency.
