Customers service layby was removed for no valid reason I want my money back

I had a very unpleasant experience I've made a layby round March 2020 the stores were closed during April because of lockdown I've received an SMS apologizing for the inconvenience but an extension would be given for the layby May (month 2) I went and pay and on the slip It showed 2 dates last due date would 9 July 2020 ,and as far as store manager has explained they even give 14 days Grace after expiring date , to my suprise the layby was cancelled and removed from the system without any notification I went to take it out 26 June and this what they told me after saying all of the above I want my money or that clothes Iayby apparently they give you a gift what must I do with the gift I dont have the desire to buy anything there they made it look like as if it is my fault but i have proof of all the till slips and I've never seen such arrogance and inappropriate behavior for over the past 20 years I've been shopping there from what I can make out someone was maybe after what was in the layby because nothing makes sense at all I'm deeply grieved by this raw deal what do I tell my children now they chose those clothes. I'm really shocked and disappointed by this whole scenario and I want my money back because I paid money not for a gift card their is no such things as I cannot get my own money back I will take it further if i have to things like this that annoys me as customer service sorry mam this how it is accept it bull****
