Worst service ever

I first bought pizza at Debonairs in Mams mall,then they gave me poor service,then I decided not to go to Debonairs again, after 6 months I decided to give another Debonairs in Silver Oaks a chance, unfortunately they too gave me worst service,I even asked for my refund, now I have decided not to go near Debonairs anymore,all of them failed to clarify me.
