Employee calls me a s***

On the 24th of April I had ordered Pizza from Debonairs Southgate at 14.41 and by 15.59 it had still not been delivered or had we received a call so we called them. The manager stated that the pizza was still on its way. the delivery guy arrives at 16.20 and we refused to accept the order. the guy asked that we do him this one favour and pay for the pizza. he continues to say his delivery time takes 2 hours which does not make sense. we then went to the actual store to speak to manager Sharon and she continued with the 2 hour story which made us upset and she continued to be unapologetic. An employee started shouted over me when I was trying to speak to Sharon and she did nothing to stop him. I eventually asked him for his name and he asked me what I want it for and refused to give it to me. after a 30 minute argument at the store we walked away as the above mentioned employee said "yes go sl*t". we have never received such terrible service. definitely not going back there!
