BAD delivery and communication with customer!!!!!!

I ordered a pizza online that I was supposed to wait about 30-45mins for. I am now at an hour and a half, the online tracking was unavailable so I called the number displayed for the store but it took me to the call centre. The person I was eventually put through to said he will check and get back to me and he didn't!!! I then called 20mins later and this girl called Lerato kept me on hold for 10 minutes without ever even getting any of my information until the phone cut!! To say I am peak annoyed is an understatement!! I want a refund and I don't even now how to go about it!!! I am ****ED.
