Bad pizza causing food poisoning

Bought the Sava Flava deal, Sweet chilli chicken and peperoni pizzas. Got food poisoning from it, as this was all we ate since having some cornflakes the morning. Calling the manager, was only met with no-care attitude, stating to: prove it first with doctor's letters and a bunch of additionals. So instead of checking their side for bad ingredients, drown the customer in red tape. Hopefully it will go away. Will never buy from them again. Westgate branch much better food.
