Disgruntled customer.

I ordered online and paid online, I specified time that I'll be collecting ( which was 1hr 30min from the order time because I was in the bank) I went to fetch my order 10 min late than the time ( deliberately) only to find out that my order was not done. They say they didn't have the ingredient. Why wasn't I called to be told this information? All my details are on the order, when they saw it, why didn't they let me know?? I was very irritated, angry and heartbroken. I went on their website and made a complaint coz I just felt the manager at the branch had no empathy or sympathy towards me and my situation instead he kept telling me about the missing ingredient that just arrived, he just didn't seem worried that an online order was NOT DONE. My complaint did not get far either because I received response saying my complaint was resolved. Hahaha is this a joke. Not once was I called by a representative of Debonairs Pizza to apologise (that's all I wanted) but I'm recieving an email that says we are closing the case, not quite what I was expecting from a big reputable company. Sooo dissappointed with service at branch and system.
