Pizza hut I paid for my order online, plus the tip and my order was never delivered! Kissimmee FL

I placed an online order April 1sy when my family was on vacation, paid for it online plus the tip amount and my order was never delivered.  I couldn't get a hold of anyone at the store,  it was all automated. Finally got a hold of someone from Corporate. They filed a complaint and told me someone would contact me in 3 business day.  Heard nothing,  so I reached out again.  Filled another and told me to wait another few days,  and I said I already did but proceeded to tell me to wait 5 business days instead now! I reached out again today which would be 10 business days now! Still nothing,  the customer service is crap! They stole money from me,  and could care less about it! This company needs to be investigated because after reading reviews,  it sounds like I'm not the first one this has happened to!
