Incorrect Lay-bye information

In March 2020 just before the lockdown i had purchased winter clothing for my 3 children at Eastgate Mall Ackermans ,at the value of about R1600 total and had placed the clothing on Laybye.I have been laybying clothing with Ackermans for years and i know laybye is 3 months and mine was due in June,however the country was placed under hard-lockdown and we have been advised to stay home.i went to an Ackermans store in Park Meadows mall in May to make payment on my lay-bye and find out until when it would be valid due to the lockdown circumstances and the cashier confirmed it would only expire on the 3rd of August 2020, it had been extended due to lockdown and the new recipient she provided confirmed the new expiry date as 03/08/2020.Just to be sure i called the Ackermans head office on the number behind the till slip in May, to confirm if information i had been given in store was correct and the consultant i had spoken to confirmed that it indeed had been extended.Yesterday i go to Ackermans Eastgate Mall to pay off the outstanding and collect my lay-bye and i am told that my lay-bye had expired in June and the items had been dispersed back on the floor.The cashier advised that the expiry date on my reciept for 03/08/2020 was incorrect and that the head office had given me the WRONG information, as well as the cashier who had given me the receipt at Ackermans Park Meadow mall and that there is nothing they can do but refund me,he further explained that there are many other customers where the same incorrect expiry dates had been given to.I am extremely upset and disappointed by the service from Ackermans as i DID NOT WANT A REFUND but was told they cant help me!!,I was not sent any communication or called in regards to my lay-bye even though the error was internal .my children are left without their winter items, that i had carefully selected for them and i could not even find the same items or even sizes on the floor, as the store now has on display Autumn items. Ackermans is such a big company and i had so much respect for you..I am beyond irritated
