Immediate payments with no immediate service

I ordered hair a week or 2 before my graduation and before making payment, i asked if they would be able to deliver before my grad and they reassured me it will be before the day and that they won't disappoint. They asked for an immediate payment which I did and gave 2 addresses of which 1 of them was closer to their business, I kept on asking when they would deliver until the day before my grad of which I advised I'll be leaving at 10am and they still advised it would be delivered before that time and only at 10:30 they texted to tell me they were tracking my order and today still I'm still waiting for my order and my grad was on the 8th of May already.
