Disappointed in service

I placed an order on the 30th of April online for dinner and i recieved no call to say that they very busy and to tell me that I will recieve late delivery. When I tried to call the store there was no answer aswell. I then decided to place a new order just incase manybe the 1st one didnt go through however even then no one called . I had then decided to prepare dinner since my food didnt arrive . After 2 hours my food arrived and I asked the driver why so late and told him that i ordered 2 hours ago. Being a good person and understanding I let this slide so I just kept the pizza for the next day without even bothering to call and make an issue of it .The next day I decide to dish for my 3 year old and myself and While having my pizza I realise there is something in my mouth .There it is someones nail..I spat it out and took a pic and threw the pizza day But I couldnt let this go because thats just unacceptable and after I decided to complain just about the nail that was found hoping that I would get what I paid for atleast but however till date I recieved 4 phone calls but still I am not happy .A Managet cannot be one sided and tell me that she checks they pizza and it doesnt look like a nail and it cant be .Are you telling me I am making a story then and put a nail in my pizza ????Please atleast as a manager I would expect you to hear were a customer is coming from .Repeating sorry sorry and keeping quite on the phone wont help the complaint. Did you call for me to speak to myself ??? Above all I am not a customer that looks for faults and likes to complain because if I did I would have when I got my food 2 hours later .. So No my complaint is not closed and resolved . I found a persons tip of there nail in my food and I am not happy at all .
