Unhappy customer

I’m very disappointed with the quality and portion of my large triple decker I bought three pizzas one of them was a triple decker. I’ve never received such a pizza before. I usually buy at vangate mall or century city but I never had any issues. But the one bought from this branch at grandwest is the worst. The pizza had no filling it was so flat I even went back to the store and spoke with the lady manager that was told by one of her staff the guy from food outlet wants is here. I also work at Grand west and I’m a Manager at the other outlet but I didn’t come as a manager, I came as a paying customer that had an issue with an order and my complaint wasn’t taken seriously because I work at the same complex as them. So I decided to leave as I was leaving I could here the staff laughing out loud and saying funny remarks and I actually wanted to go back and ask for a refund but I didn’t I’ll never buy at that branch ever again. What a waste of money I’m very disappointed
