frustrated customer due to unhygenic condition

I visited Seabelles restaurant in La Mercy. Whilst endulging in my meal i noticed a ****roach fall of the table on to the floor. i over looked the ****roach, and whilst continuing to enjoy my meal almost half way through the meal i noticed a cooked in fly in my food, it was a very big ugly fly. i immediately started puking on noticing what i had almost eaten. On calling the manager Niresh to my table, informing him of what was found in my meal,his only response was that it was normal to have ****roaches and flies in food, and i shouldnt make a issue out of it. The waiter Shireen thereafter approached the table, very arrogantly stating that i must shut my mouth and get out of the restaurant. There were a whole lot of customers in the restaurant , which made me feel humiliated , degraded. As i stood up to leave the restaurant, Shireen and Niresh kept saying shut up and get out, which was extremely unproffesional. this matter could of been resolved in a more amicable way, however the waiter and managers theory was that it is normal to consume these disgusting flies. i immediately emailed the owner Tony of the incident , to date he has not contacted me or responded to me email.
